I used Petit EZY Prime and Petit topside polyurethane paint over it on my RV8. I’ll try to attach a couple pictures, but if that doesn’t work, send me a message and I’ll email them to you. I got these products at my local boat store and they have held up very well so far - 66 hours, so not conclusive - but it still looks shiny and new with no delamination or bubbles. I can easily wash off oil drips, etc with soap and water. It’s a shiny, glassy white, that’s easy to see any drips, etc. I did a coat of the primer, squeegee in to fill pinholes, sanded when cured (cured quick), applied a second primer coat with a high density foam roller and then sanded that after cure. Then two coats of the the topside paint, sanding between coats (cured for one day). It looks great, especially for the inside of a cowl!

I tried that, unless you thicken the epoxy and put it on really heavy it won't cover the pink. I am going to shoot the inside with a coat of white paint still....

I used Stewart Systems EkoPoxy in Smoke Grey. Very easy to apply. Very durable, so far (80 hours on the clock at the moment). The EkoPoxy won't kill you when you apply it, which is kind of a nice feature... :-)

I did the simple way on the last two planes, a couple of coats of white primer (PPG DP-48LF). Looks good, seals, is very durable and the stick on aluminum radiant heat shield stuff from Van’s stays on.

I sanded and filled just like the exterior composite surfaces. I painted it white with regular automotive catalyzed paint. It’s been very durable and I’m really happy with my decision to finish it to a high level. I chose white for the same reason as DanH... you can see every little drip or exhaust leak or fuel leak or whatever. Very easy to clean with mineral spirits.

I’m referring to my Midget Mustang, but it makes no difference in this discussion.
