While we are fine tuning John's post, I should mention that his calculation (as he states) assumes 100% solids, certainly not the case for most polyurethane two-part paints. Probably they run something like 30% VOC, so that 2.25 ounces of applied paint probably results in about 1.5 ounces of weight after the volatiles have evaporated. In any case, John's point: ***adding weight to an ultra-lightweight paddle just to restore the gloss is a minor folly*** is well taken here. -- Dave Kruger Astoria, OR who likes his paddles scratched and dinged *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
