I'm preparing for a Pinewood Derby for the young boys at our church, and getting supplies together, so I can help those boys that may not get the support at home, to build their cars. I'm also going to build an "outlaw" car myself, just for kicks and giggles.
I was about to go get some wood sealer, but it occurred to me that I have a can of polyurethane finish, and was wondering if this would work as a wood sealer, in preparation for painting the cars. Also, can enamel paint or acrylic enamel paint be painted over the polyurethane, with proper adhesion and no reaction? Would a 2-3 day dry time between applying the polyurethane and applying the paint over the top, be sufficient to avoid issues?
If the polyurethane won't work, I have no problem getting some wood sealer. But I have already spent quite a bit, getting specialty Pinewood Derby tools and supplies. (My wife thinks I'm crazy for it.) And I hate waste, so I don't like the idea of buying a good sized container of wood sealer, that we will only use a very small portion of. Then it may sit on the shelf for years, until I realize it has went bad, and throw it out.
Anyone with any experience on this subject? Please share.
