P-31 / Barrier Coat

« on: March 31, 2017, 03:06:21 pm »

After 30years of accumulated bottom paint (Lunasea P31-2 Hull # 82), I had the bottom soda blasted.  My question is, since the original bottom did not have a barrier coat (it had something called Blister Bloc in the resin) do I need a new barrier coat before bottom painting?
Thanks in advance Larry Conforti (Knapps Narrows)
