I'll second that.? After all the chemicals I encountered in the course of drilling and filling and covering my 15s hull BWL, the 202 was the only stuff that once made me drop everything and immediately leave the shop for fresh air, and I was working with doors open and good ventilation.? And yes, it took out more than one pair of gloves, too -- just dissolved them, as you said.? With hindsight, I'd have had a few pair of chemically-resistant gloves on hand. Forearms should be covered, too.? Application of barrier cream would be wise.? Safety glasses are essential. I overpurchased on the 202 and have about half a gallon left.? I half expect it to eat through the metal container. Good parts cleaner, though, so I probably won't take it to the hazardous waste center for a while yet. -----Original Message----- From: Joe Murphy <seagray@embarqmail.com> To: For and about Montgomery Sailboats <montgomery_boats@mailman.xmission.com> Sent: Tue, 26 Aug 2008 8:41 am Subject: Re: M_Boats: Bottom paint/barrier I'll add that this solvent wash is extreeeeeemly caustic. I disolved my vinyl gloves right off my hands. So be careful. It also destroyed the seals on my Timex watch. So all the buttons don't work.

Several new owners have commented on getting barrier coats or paint onto their hulls.
I just did this, reluctantly but necessarily, due to a gelcoat blister problem.
I was a first-timer and, so, studied up on it for a long enough time that folks probably wondered if I'd ever wade in.? One important bit of instruction came fairly late in my reading, but I was able to take advantage of it.? I've forgotten now whether it was West or Interlux or both, but recommendations were to not only sand (if and as necessary -- with several hundred small blisters, it was necessary in my case), but to clean the area of the hull to be painted, with the strong solvent intended for the purpose of dissolving the waxy component in the surface of the?gelcoat, as well as any residue of fiberglass mold release agents.? Interlux' version is Fiberglass 202 Solvent Wash.? I believe West's is called "Thinner and Dewaxer."
Otherwise, you're applying your expensive barrier or antifouling coats over a slick, waxy surface, to which they may not adhere reliably.
Maybe this is widely known, but the references here?to getting paint on the bottoms haven't mentioned it, so I thought I would, for those whose work is still ahead of them. _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats
