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. Rick Langer M15 #337

Did you use "marine" Penetrol, or just whatever you could find at the local Lowe's, whatever?

This is an old thread, but I wanted to follow up on the advice I was given. 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,

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.

Hi Craig, Before I buffed out my 17, it was extremely chalky - not a hint of shine to be found. I first used a "regular" car-type buffer with the compound and it wouldn't touch it. I thought it was a lost cause. Then a friend loaned me his big, metal, Milwaukee buffer - has about an 8" pad. That did the trick and my boat ended up as shiny as new. A few years later I repeated the experience on my friend's Westsail. No luck until we rented one of those buffers, then shine. One other note: On my Monty I tried a few different compounds, and finally settled on the Meguiar's Heavy Duty Oxidation remover, followed by their two other products (recommended on the first one as the follow up steps). It's been so long now that I don't remember specifics, but one of the two follow-up products has a brownish tinge to it, and I had trouble with it staining my off-white gelcoat. Years later, when we were doing the Westsail, we were in a large yard with a professional staff (working on *other* people's boats, not ours, alas), and we had the same problem with another compound that was tan colored. One of the pros recommended a 3M product (white) and it worked very well. I can look up what it was if you have a problem finding it, but it comes in a tall, cylindrical plastic bottle that's about 1 quart in size. Has a purple label (for sure). Might be Imperial Microfinishing compound. On some stubborn spots on the Westsail we used very fine wet/dry sandpaper (which I'd also had good luck with on the Monty) - just using it by hand, not with a sander. I think we started with 1000 grit (600 grit on really bad spots), then gave a few swipes with 1500, then 2000. At the time we though the sandpaper was maybe a bit harsh, but in the end we noticed that the sandpapered spots looked even better than the rest. Then, last summer I worked at a marina that had a fiberglass expert on staff. Amazing the things that guy could do with fiberglass. At any rate, one day a customer came in asking about what product to use to buff out his boat and the guy recommended just the wet/dry sandpaper - no compounding at all. I'm still amazed at how often I pass boat-owners (and paid laborers even!) "buffing" boats with those little car buffers and ending up with almost no shine. If only they knew how much better the big Milwaukee works! That being said, it does have some power to contend with; ran away with me a time or two... (when I went to repair the cord on the rental I could see that I wasn't the first, either :-). I haven't used Penetrol.

I believe it was just a straight spin. When I did the Monty, I really pressed and never had any signs of burn. On the Westsail, which was owned by a friend of mine (also white gelcoat), he did the power buffing (thank g-d) and at times he was buffing hard enough to actually slow the machine down a bit (of course he let up right away) and still no problems. As long as you "get" how to control the spin (have you ever used one of those janitorial floor buffers - now there's some hysterical laughter the first time) it's fine. I should see if I can find a link to one online, so we know we're talking about the same thing. I think they're pretty common at rental places, then I bought a 3M buffing pad/wheel. It's a lamb's-fleecy looking thing with a nut impregnated in the center which goes over the spindle on the buffer. One's good for a whole boat. I'd be happy to get more specific on products etc. if anyone's actually going for it. I could do a little online research - or perhaps find some of the things in the WM catalog for reference. --- Rachel

:-) Yeah, I fell for one of those too.
The closest thing I have is a Dewalt high-speed angle grinder, but I don't see any sort of reference to the ability to put a buffing bonnet on it. http://www.dewalt.com/us/products/tool_detail.asp?productID=145 I'm sure I'll be doing a lot of serious buffing, so if it's not too much trouble, if you could point me in the right direction I'd be grateful.
