I am using a minwax spray poly satin on my build. My question is how may coats should I use. I have a good 6 coats on both the body and neck now. It is hard for me to tell the build up since it is a satin. I will likely only hit it slightly with some 0000 steel wool to smooth it out. I am going for a "natural" look finish here but I want to make sure the Korina and Zebra wood are protected. I did not use any grain fill.
