Hey Friends, So i've stripped this Strat Plus body down and am expecting some products to paint and finish this rebuild from Guitar ReRanch. one of the products is a grain filler, which i've never used before, but i don't expect it to work as a substatial filler for these craters. I've recently learned that in the 90's Fender used a veneer and my paint stripper got a little too hot a couple of times. What do you think would be the best filler for this application. From ReRanch i'm getting the oil based grain filler. i've got sanding sealer, then the laquor based primer, the aerosal paint and the nitro finishing coat. So what's going to stick the best to this alder under these layers of finish?
