Hi Guys.

I have recent completed a Tasca kit so moved onto painting the vinyl tracks included in the kit using tamiya flat black.

Once i finished painting the tracks the paint just chipped off....

Has anyone else had this problem? if so does anybody have any tips to solve this issue?

i look forward to hearing from you.

Cheers.

Brad

Hi Brad,

painting flexible plastics is always a kind of a problem due to the nature of the product (it contains a lot of chemicals that soften the product but they make glue and paint adhere much more difficult). I can think of 3 options to solve the problem:

1) clean the tracks with a lot of soap and don't touch with your hands afterwards. I would stay away from chemicals they might ruin your expensive Tasca parts.
2) use a proper primer, can be any kind as long as it can be applied in thin layers. Many people use cheap automotive primer or primer from Gamesworkshop.
3) use enamel paint, this tends to stick better. I found out that Humbrol sticks to anything.


Try them in order 1-3-2 I would say to keep costs down.

HTH,

Matthijs

Best answer is to prime with a lacquer based primer. Tamiya Grey primer will stick to anything, and give you a great base for paint to adhere to. If you prefer to use a rattle can, then go with any old lacquer grey primer from a hardware store. Just spray outside as those cans have a very wide spray pattern, and put out a lot of primer.

Anything vinyl needs to be cleaned with warm water and soap, then rinsed very well. Air dry, then paint away.

Hi

I wouldn't use a Laquer or Alcohol based paint or primer with Tasca tracks, there are lots of reports on the net of Tasca tracks falling apart 6 months to a year after painting when stong solvent paints have been used. A good wash and a water based paint is all that is needed, I use Vallejo on mine without any problems.

Paul, Thanks for the info. I've yet to build a Tasca kit, and sure wouldn't want to ruin a set of tracks out of stupidity. I've had my issues with Vinyl tracks, and painting them varies from manufacture to manufacture.

I painted Tamiya tracks with a coat of their lacquer Grey primer, then their Acrylic paints, which are really alcohol based, and all went well. I just had a complete failure with the Academy vinyl tracks and the Tamiya primer. Once dry, it just flaked right off. I repainted with Model Master acrylic paints, as they're water based, and the paint stayed on. What I couldn't accomplish was gluing the track ends together, as melting the pins as suggested never works for me. I tried CCA glue and when dried, just flaked right off. There are some specialty vinyl glues out on the market, but I haven't tried them as yet.

I always just spray them with enamel, let it dry, then cover that with acrylics in the colors I want. And I staple the ends together. That way, I can be sure they'll never come apart.
