car colors for models?

Postby trek3159 » Sat Jan 11, 2014 11:24 pm

Hey, guys, was wondering if rattlecan paint for cars would be safe to use on models (resin or plastic). Chevy makes a light gray that is almost white that I thought would look good on TMP era starships. Any one ever use this stuff on their models?

do you mean rattlecans for real cars? (usually lacquer-based)
or for scale cars (usually petroleum-based)
if it is for polystyrene plastic then the answer would be yes.

I've used auto colors on resin. I have not tried in on styrene, but as I don't paint without a primer i don't see it being an issue.

I once used krylon primer plus color. bad news. I'd stay away from anything offer extra coverage or such.

You have to watch mixing some paint types.

I personally use acrylic as my base color (I ALWAYS use primer) for all of my styrene kits but that's only because I found a color that works for pretty much any starship, regardless of era. It's a craft paint from Apple Barrel called Dolphin Gray. I'll post some pics of it in action later but it thins very well with either Future or Tamiya/Testor's thinner for airbrushing. I go 2:1 or 1:1 depending on what works better for the given project. Another reason why I base coat with acrylics is because I detail with enamels. When I detail with enamels, I can use mineral spirits to clean up any flubs without affecting the acrylic base.

As far as using the rattle cans of auto paint is concerned, you should test it out on sprues first. I use auto colors right from Pep Boys (Duplicolor, Krylon) for my resin prop kits and have no issues at all. That being said, I sprayed a bunch in a Solo plastic cup last night to brush on the fine details and it melted right through the bottom of the cup and I'm pretty sure those cups are styrene.

I do believe it's a different story when you use primer and I don't believe that auto primer is lacquer based (or at least it's not the same animal as the paints) because I'm pretty sure that I've used Duplicor primer on styrene kits with no problem. Again, it never hurts to test on sprues first.

Yes they can be used. However a word of caution,

1- Use the correct primer for the paint system you are using.
2- Use light coats
3- Be aware that some plastic crazzing WILL take place. ALLWAYS when using a laquer base.
4- ALWAYS Use a primer sanding sealer

Hope that helps. Let me know what paint manufacture is an I can try to help further.

Did I just see your work on Face book? A Nebula Farrugut? If so it looks awesome. It's a great color.



Ya did, and thanks for that! And thanks for being a member of Friends of Drex!
