Thinning for Spray
Im about to spray Interlux Epoxy Primecote with their branded spray reducer. I have a gravity fed spray gun for the job but have never sprayed Interlux paint before. Does anyone have any suggestions on how far to thin down this paint before application? I've read about time targets with a zahn or ford cup but I don't own any of those measurement tools and don't plan on purchasing them for a one time boat job. Any consistency suggestions? Thanks.
p.s. before anyone asks, I do have a PAPR respirator and will take all appropriate safety precautions.
