My niece has asked me to help her with her high school science project: a baloon air propelled car. The car will be made out of copper pipe and wood.



This is a good opportunity to teach her how to paint. (She's pretty keen on this project , almost as much as me ) We want to give it a killer shiny red paint job. I've got all I need to shoot automotive paint. (etching primer, grey primer).

-How should we prep the wood to accept automotive paint? I'm worried the paint might sink.
-Also, will etching primer stick to copper?
-If yes, should we mask off the wood from overspray before the etch and grey primer?

Any advice is greatly appreciated. We're starting "the build" this Saturday.

I don't think I'd use auto paint on wood. I'd probably use Krylon paint in the aerosol can. Cause it can be used on wood. Why go to all the expense for a project that will only be used once. Make it easy on yourself. Good Luck!
