LAC: Longest lasting "Wax"?

[David Ullrich]

Hey all,

Although its not for my Audi, this could easily apply to any Audi. I'm in
search of the longet lasting wax or wax-like product for use in a harsh
environment. Specifically on my fiberglass blat. She's an older 40 foot
trawler (a Willard 40 FBS for those familiar with trawlers). Her hull is
white with a grey boot stripe. The hull is oxidized (clalky). I can gt rid
of the chalkiness and oxidation with a polisher and cleaner/compound. She
has plenty of gelcoat left for that. If it comes down to it, she actully has
enough gel left that I could wet sand then polish, but I dont thing shes
that for gone. But the real question is what wax or wax-like product to put
on to keep it looking good for a long time to come. I dont need super high
gloss, the most important thing to me is longevity. She is outseide and in a
slip, constantly exposed to the elements including salt air. I am good about
rinsing her down with freah water after I take her out, but she is exposed
to saltwater at least one a month.  Idealy I'd like it to last at least a
year, if not longer. SO, anyone have any suggestions for a long lasting
product?
