Post subject: Penetrating question
Archived from groups: rec>boats>cruising, others (more info?)

I've got a fiberglass boat which could use some luster restoration. I've
heard reports, but none first-hand, about Penetrol. Some have said direct
opposites - that it gives a great, deep, restoration, and that it doesn't
work, and causes long-term dullness, but I don't recall any who had
personally used it.

If there are any here who have personally used Penetrol to restore
fiberglass gelcoat luster, I'd be interested to know the results - were they
good, bad or indifferent, and would you do it again/how long did it last/did
it have negative long-term results, etc. In particular, any who have done
so on glitter surfaces would be welcomed.

Since I don't get here all that often, a direct response as well as to the
group would be appreciated. myname at earthlink dot net is more reliable
than the uga one....

Thanks.

Just like their car products, Meguiar's Fiberglass Restorer works
great on gelcoat. Someone gave me a free Sunfish and Meguiar's made
it look almost new, except for the obvious repairs....

Penetrol looks good for the first few months, then oxidizes with a
yellow cast.
Best for gelcoat restoration is to wet sand off the oxidized surface
with 2000 grit wet and dry followed by power buffing with a high speed
autobody shop buffer with pure lambswool bonnets (1 bonnet per grit
size). Polishing grits used in sequence 1000, 1300, 2000. Followup with
an application of carnauba paste wax applied with water and hand rubbed
into the pores, followed by a power buff.
Process will usually restore gelocat to NEW condition if there is
sufficient depth remaining, otherwise paint the sucker. Thbe above
process is what is done to a NEW hull when its pulled from its mold to
remove irregularities, hazes and blemishes.

If you keep the gelcoat (new or restored) fully sealed with wax to
prevent oxidation you wont have to restore it. BTW - stip any wax
yearly with caustic to remove the oxidized wax which will promote
oxidation of the gelcoat.

There are several snake-oil treatments on the market that cover the
oxidized gelcoat with a polymer ... and they look like hell in
comparison to a buffed and restored hull.

Well, great! Two diametrically opposed opinions about Penetrol. I have a
heavily oxidized, older fiberglas boat and am not anxious to start wet
sanding, etc. Might have to though...

Any other pros or cons re Penetrol?

We've started using it and Bob likes it fine. It makes the boat look
really great. I'm not sure if we'd know if it yellowed though because
our gel coat isn't white - it's kind of beige. But the guy across the
dock has used it on his white boat and we haven't noticed any
yellowing.

In any case, I don't see much difference between the effort involved
in doing all that sanding and waxing business and stripping it off and
redoing it periodically (or giving up and painting the topsides), and
in using something like Penetrol and stripping that off and/or
reapplying it periodically. And since the Penetrol requires much less
effort to begin with (and we also use it in the cockpit etc), I'm not
convinced that it is worth my time or the money to pay someone
(because I totally wouldn't do either one myself) to do the buffing
and waxing thing. It isn't worth it.

Thanks to all who responded to this thread. With one exception, the
responses were uniformly negative about Penetrol, and we've decided to go
the traditional rub and buff route. I want any boat I sell to look as great
as when I sold it months down the road :{))

Thanks again.
