Just about any dry film will hold up to gold plating if the bath and tank are optimized. I have seen the cheapest dry films performing well in very efficient baths (some accounts have even introduced air agitation to scrub the hydrogen gassing from the surface. I thought this was a no-no, but the account insists they are getting good plating. One account was in China and one in Europe.) The performance of the resist is directly proportional to the amount of effort and costs that you put into your gold plating environment. In marginally efficient bath environments, select a plating resist with high adhesion and alkaline resistant characteristics.
