TVT - Mail/Inspection Motor
Re: TVT - Mail/Inspection Motor
A similar trick from my 4mm days was to use Rizla cigarette papers. Spray one the colour you want for the lining background, then draw a line across it in the central colour using a bow pen or Rotring pen. Then use a fresh scapel blade to cut as close as you want either side of the line and hey presto you have, say, a black line with two white borders. The cig paper will stick to the weted model surface and can be manouvered to the right location with a fine paint brush and will follow fairly tight corners. When it dries out a quick squirt of varnish will seal it in place.

No, the clear coating on blank waterslide decal (transfer) paper takes enamel paints nicely. I wouldn't use acrylic paints on a bet though, so I've no experience with them.
I normally don't do any surface sanding on polystyrene and ABS, or use a primer. The only time I've used primer on a plastic recently was when I painted the sleepers before laying the track in the garden. They were moulded in either polyethylene or polypropylene and I used plastic car bumper primer so the paint would stick. It's lasted out in the weather for two years so far....

Very interesting that you don't 'sand' styrene. I usually use 'scotchbright' on styrene before painting, then wash.GTB wrote: ↑Wed Dec 30, 2020 12:02 pm

I can almost guarantee the spray enamel I use will craze with no primer, and may still craze when primer used.

Re: TVT - Mail/Inspection Motor
Hmmmm, I wonder........
I do all my model painting with an airbrush and enamels and I've never seen any crazing on either injection moulded kits, or polystyrene sheet. Even back in the ‘80s when I used Floquil I had few issues, although being a lacquer that had a reputation for attacking polystyrene.
However, I've never used aerosol paints on models. With aerosol cans, there's little control of application rate and no choice in the thinner used, so I guess the risk of solvent attack on the primer, or the base plastic, would be higher.
I degrease polystyrene before painting with detergent and an old toothbrush, but that's all.
