Good day, all!
I've run into something that I haven't seen before and wanted help from the experts.
I am finishing up a Russian Alfa buildup for a customer using a customer-supplied hull of unknown origin. Main hull castings are crisp and clean and are laid up in nice, thin epoxy. The issue that I'm running into is that the rear horizontal stabilizers seem to be weeping out a sticky substance through the paint. Prior to priming and painting, the fins were washed and scrubbed with solvent, sanded with high grit paper, then primed and painted.
I'm assuming this is the result of improperly mixed resin during the casting process that is post-curing somehow, but I'm not sure. Regardless, I'd appreciate advice on how to stop the madness from occurring more.
Thanks, in advance!
