GH Rocketman:
Even SIG sanding sealer is not the first step? Hobby lobby sells this right by the pinewood derby section. That stuff is so thick, I thought its supposed to fill the grain first then use whatever to provide the surface gloss. Also, does dope based products eat wood glue joints? Also, is SIG or any other clear dope even needed in rocketry? I've tried delta creamcoat and fnf: personally I don't like either one and the aerogloss blows em away but that dam smell............. Good luck with your pinewood derby cars!!!!! I'll be cheering(virtually that is) Take care, Jeff
