It's the miracle restorer alright, Rik! I wonder if it works on the scalp. :-) Actually, you can thank Larry Yake, Tullamore's ( http://www.funtigo.com/MSOG?b=197153&c=1789789&p=start ) caretaker. I thought I recalled some threads regarding "marine" Penetrol versus "hardware" Penetrol, but I've only used what I could find at hardware stores. When I finally get the tarp off my 17', I'm gonna buff out the hull with a good waxless rubbing compound, then Penetrol, then wax. My gelcoat is pretty tired and I doubt I'll get a great result, but I'll do what I can to get the best possible result. --Craig ----- Original Message ----- From: Rick Langer To: montgomery_boats@mailman.xmission.com Sent: Monday, June 06, 2005 9:21 AM Subject: Penetrol Hey Craig, I used hardware grade Penetrol, as you suggested. Thanks for getting me started with it. I just gave half of what's left to a friend who was so impressed with the results that he's going to use it on an old Mercedes. This Penetrol is the Marvel Mystery Oil of fiberglass finishes. BTW, for all that have been following this hot story, after soaking my roto-till engine with MMO for three winters, it now runs very well. I was using MMO to free a frozen ring that I was guessing caused the low compression. I didn't re-check the compression because the engine runs fine.

Yesterday I compounded my very oxidized blue hull. The results were ok but not great. Then I put on a coat of Penetrol. The results are spectacular. Except for the dings and scratches the blue hull looks new. I wasn't able to wipe it off after application because it dried too quickly. Next time I'll do smaller areas at a time. The finish I got is high gloss. Thanks, Rick Langer M15 #337 Hudson River
