I recently used the Krylon single stage Epoxy appliance paint and if I remember correctly you have initial short recoat time when applying the paint and then must wait several days (1 week?) before recoating with the same paint. Other wise it will cause blistering or ripples.

I would stick with the duplicolor and not mix them with krylon or other different paints.Could have unexpexted results later from the nitro fuel.

I also would recommend a Urethane clear that requires a hardener and believe that you can use the urethane over most painted surfaces. It is always best to test the paint you're going to use before applying any clear coat.

As a matter of fact you could probably use just about anything you want for base coat paints if using a Urethane plus hardener clear coat system.

As far as sanding tape lines from the different colorsI would lightly wet sand using1200 to 1600 grit wet to flatten anyraisededges of paint from doing a color scheme. The Clear Coat should produce a nice flat finish after the light sanding, even with a metallic base.

As far as nitro proof any two stage (clear with hardener) should provide a very tough surface (fuel proof).

You really need to invest in a compressor of some sort as what you're using for your projects sounds like a real PITA.

I got this setup from TCP Global for airbrusing.

Comes with a Badger Crecendo airbrush, a really cool airbrush compressor with a one gallon storage tank for positive air pressure at the airbrush tip, a airbrushstand, a really cool cleaner jar forcleaning the airbrush, aset of Createx Paints, mixing utensils.

You have a choice of airbrush I believe and get an Iwata if you prefer.

Check out the Ebay TCP Global website and their regular website http://www.tcpglobal.com/as they have all the paint and painting tools that you could possible need. The Realistic Live Fire Flame kit is freaking way cool! http://cgi.ebay.com/ebaymotors/AUTO-...item2eb7581f7e

The Auto Air colors are a water based paint that's compatable with just about any Clear Coat system available and comes in pearl, metallic, transparent, Candy. etc
