The Little World – Thick And Sticky

I have revisited my childhood and I’m thinking that things has changed down the ol’ hobby shop.

As a kid in Canada I had access to basically four brands of model paint – Revell at first, then Humbrol, Testors, and Pactra. Enamels all, with different characteristics and markedly different vehicles.

The smell of the paints was a clue to which they were – you could tell a puddle of Pactra from a similar amount of Humbrol with your nose. Revell was lousy paint but it had a particular odour – probably sourced from Love Canal. Just as well I graduated to Humbrol early.

But earlier in the year I tried Humbrol 22 – gloss white enamel from the familiar little tin. I was flabbergasted at the thickness of it. Admittedly it was a cold day here in Perth, but it was a cold in Calgary too and the paint was never like this. Fortunately I was not going to brush it on – it was destined for airbrush use and I had purchased a bottle of the recommended Humbrol thinner for it.

Thinning is a sometimes art – more akin to alchemy than science. I use a souvenir teaspoon as the basic measure of quantity and dilution, and am getting pretty good at estimating the amount of paint needed for any particular job. This is a doddle with the acrylics as they flow so readily. But this Humbrol needed two scoops and three dollops before it even approached the consistency of milk. It did go through the gun successfully and it did coat the job, but I made sure that I flooded out the mechanism with about 5000 gallons of mineral turps afterwards to clean the nozzle.

I was undecided about whether I wanted to move back to enamels or not. Next coat on the job was a matt brown – I still used Humbrol and see if it was any better. I was not prepared to reject a useful tool that others seem to employ based on just one experience. If it allowed for multi-layer effects that were less prone to dissolution than acrylic, I decided to continue to pursue it. I still had that much affection for dear old Humbrol and I had always thought their tins the cutest thing in the world.

Addendum: Next day analysis showed that the sprayed 22 Humbrol had done as well as could be expected – given that it was covering a dark plastic with no undercoat. The test wasn’t as fair as it might have been, and should not be taken as gospel. I thinned the tin mix slightly and used a brush to re-coat the job, and it came out splendidly. I was wary of touching it for a week, however, as this was not good drying weather.

I’ll suspend judgement now that warm weather has returned – time will come to try another colour or consistency.

The Little World – The Thin Coat Revisited

I have bemoaned the price of good-quality modelling paints before here in this column, and extolled the virtue of using 1:1 scale paints from the hardware store as a substitute. This is valid and viable to a certain extent, but the range of spray cans in the local DIY or Bunnings is surprisingly limited. Oh, not if you want to paint wooden decks or bicycles or lawn furnture…perfect for that…but dismal if you want authenticity.

So we turn to the Humbrol, Tamiya, Pactra, Testors, or Mr Color racks at the hobby shop and more little glass jars. One day I am going to have my own weight in empty little glass jars…as opposed to having my weight in money. But after yesterday I think I am going to stop complaining – you see I finally looked at what I was actually doing with the airbrush.

Up until now I loaded up the medium cup of the brush with whatever thinned paint I was spraying and then did the classic sweep-and-trigger like I did in the Pactra spray can days. I got a good coverage eventually but a great deal of that medium cup went on either side of the work and out through the exhaust fan.

Today I screwed on the small cup – the one with the open top – and shot green for some truck wheels. No big deal, but the small size of the reservoir made me concentrate the spray more over what I was doing and there was minimal overspray. Consistency must have been good because the coats went on with no pooling or streaks. And the amount of paint used was very much less – so economical that the higher per ml cost of the hobby product was no burden.

The joy of being able to go back to the big paint racks is wonderful. I can apportion the cheap greys, whites, and greens for building sides and these can be Bunnings supplies, but I can feel better about spending a bit more on the tiny bits.

Note: Full marks to the people in Hobbytech for their advice re. thinners and paint brands. There is a confusion of systems out there and I made a few bad choices off the rack – the counter staff realised that I was headed for trouble and gently steered me back to get the right combination. This sort of help is always appreciated.

Doesn’t Matter If It Is A Front Porsche Or A Back Porsche…

It’ll still be grey…

That’s an old Canadian joke, and I’m qualified to tell it. In North America there are three colours for the front or back porch of a private dwelling; unpainted  ( and weathering badly…), grey, or salmon pink.

The unpainted ones are seen in the hillbilly states where money is tight and in the New England states where there is more money but the people are tight. They are also traditional in the maritime provinces and out in the bush in B.C. Doukhobors take it further and never paint anything else on the house – it means they blend into the landscape better when the Mounties come searching.

The grey ones painted with a special mixture that consists of any paint in the garage that has not entirely dried out and is contained in a tin that can be prised open. All the blacks, whites, greys, and lesser colours are poured into a tub and mixed up – this gets slathered over the porch. Sometimes it is glossy and sometimes it is matte, and if you don’t get it all done in one day you risk getting both finishes at the same time. No-one ever cleans and saves their brushes after a porch job – it is generally considered hygienic enough to throw them in the nearest bushes.

The salmon pink is also a mixture made from all the brightly coloured tins that have been left over after painting bathtubs, soap box racers, and Finnish houses. It is distinctive and memorable, and no-one ever really thinks it is going to turn out that shade. Not even the salmon. Note that one car maker actually made a car – a small Hyundai sedan – in this exact shade, and they made them deliberately…at least I think it was deliberate. I can say I have seen them about 10 years ago here in Perth. Short-lived, unfortunately.

These vehicles are enthusiast’s cars seen in Sydney and Perth at car shows – though there are certainly a number of Porsche vehicles on the road at any one time – including a somewhat unexplained SUV with curves named after a variety of pepper. My contact with the marque has been very fleeting – an associate of my late father owned a bathtub Porsche in 1966 and there were some occasions when it was repaired enough to go on the main roads. I believe it had prestige value at the time, though the real value may have lain in the pile of receipts from the mechanics. I remember he had the rubber shock mounts between the body and chassis replaced at one stage of the game and the cost equalled the price of my new Renault sedan.

Have I ever wanted to own or drive one? Not really. I do covet the Audi TT and I would love an early 1960’s Volkswagen Beetle in perfect condition, but the sporty Porsche has never rung my bells. I remember James Dean.

 

 

The Little World – You Need Not Listen When They Tell You…

Do you remember when they used to tell you things? Like not to sniff glue or make sure that the drill was grounded before you ran it through the wiring? You always assumed that someone knew better than you and that they were telling you something for your own good. That was what they wanted you to think.

Pretty much how North Korea and your local Centrelink office do right now…and hasn’t that worked out well…

So now I am going to suggest that you cross the flux streams, cut the red wire, and make up your own damn mind about what to do with your hobby. You may be pleasantly surprised.

Case in point: I needed to paint the front of the Goldfisch Tivoli cinema on my latest diorama – a light blue with dark trimming. It’s a large fascia, and there was no way it was going to get done on one bottle of Tamiya acrylic paint – and no-one else had a light blue matt paint anyway. So I determined to mix my own, which is what they tell you never to do. Sort of like ” Don’t sail west Christopher, or you’ll fall off the edge…”.

Good cheap paint is hard to come by these days. If it’s good, it has a price tag that looks like a phone number. If it’s cheap it has the consistency of sewage. But you can indeed find the right combo if you go for the pots of sample paints that the good paint makers put out. They are tasters to let you get hooked on their big-ticket pots…but if you are a Little Worlder and prepared to do the old Dr. Chemistry dance, you can make them into custom colour.

I got the plain white Dulux in a sample pot for $ 2.00 off the clearance shelf. I already had used one on another structure and cleaned out the empty pot. Into this crucible went  1/3 of the sample white, 60ml of water, a little Tamiya X-20A thinner, and a couple of dollops of Tamiya Flat Blue. The important thing about mixing custom colours is not the exact shade that you get, but making sure that you mix enough into the pot for the entire job. Sacrifice 10 ml at the end if you must, but do not run dry at the last post and try to re-mix it. You will fail.

Okay, ingredients in place and shake mixing all done, it was time to apply the stuff. it was going on foam-core board that had been prepped with Tamiya undercoat so it was bound to go on fairly evenly. But there was no way I was going to try to thrust this soup through my airbrushes. Fortunately I had a set of foam brushes from Bunnings – laughably cheap trim items that you would think were just throw-away junk.

Not a bit of it. Given a medium thin mixture of flat paint, the Chinese foam brush is an awesome implement. I got even coverage and no bubbles. Easy clean up, and the brush looks untouched. All this for pennies!

The front of the Tivoli is done. The coat is great and the trim strips are setting it off marvellously. All-up it might have cost $ 1.75, and for the nollekins modeller, that is extremely good news.
