Hi Jake, I`m not an expert myself, but I don`t leave lint on my finished work either. Truthfully, I`ve not worked with that Permalac product yet, but I suppose the fix trick may work as well with similar already applied and dry compounds. Actually, the procedure of applying a coat,let dry, fine sanding, applying another coat... is a standard procedure with a clear polyurathane for protection and nice finish surfaces. This product is very prone to leaving tiny little bubble bumps specially on the first coats on a porous surface. Its recomended that the coat is quite dry, and I even use a soapy water solution while sanding for a smoother finish, and don`t even get to 600 grit, 220-300. Though, the 600 will take you longer to get the bumps, you`d get a near perfect finish, so yes I`d say Nick`s advise is quite right! Good luck Jake. Nelson.
