If you are mentioning "Petit" you may have seen my post from a few years ago
RE. primers. It's actually "Pettit" and I remember mis-spelling it! Maybe
not, but it seemed a little coincidental. Anyway, the product that I used
was called the "Underwater Metal Kit",
http://www.petitprod.com/products2.asp?Productid=57&Catid=3&SubCatid=9 ,
which I purchased from a marine supply house locally. It consisted of a
catalyzed bare metal primer and an epoxy sealing primer. The repair I made -
not a seam, mind you - has gone through two years here in coastal Maine
without any sign of rust returning. However, please note - these products
are not designed to be used over rust - they are specified for use on bare,
bright metal only. In making my repair, I cut back to bright metal, primed
with the Pettit products, then used body filler, cheap primer and regular
color-match paint to finish the surface. Pettit does make a primer suitable
for application over rust,
http://www.petitprod.com/products2.asp?Productid=39&Catid=3&SubCatid=6 ,
but I have not had any experience with its use or effectiveness.
I did use a POR-15-like product in several spots and it has not been
effective. I don't think this is any shortcoming of the product, but rather
that my application was flawed. I think that if one removed as much rust as
possible and, most importantly, eliminated the cause of the rust, that
POR-15
would be effective. What I mean is that if you have rust coming from inside
a body panel and bubbling up to the outside, and you wire-brush and apply
POR-15 from the outside, the rust will simply bubble up through the POR-15.
It may be a good product, but is isn't magic and cannot substitute for
proper
removal and containment procedures.
I found an excellent and well-illustrated book on rust repair in my local
public library - I feel a bit silly bringing it up as I cannot recall the
title, but it was from the Classic Motorbooks series, and it was out of
print. I'd highly recommend it as it addresses causes, preventative measures
and repair procedures for many rust types and body situations. I will swing
by the library again when I get a chance for the complete reference.
Also, Marshall Ruskin posted what I thought was an excellent procedure
for seam rust repair to the list on 4/19/00 - Subject was " Re: Seam
rust. Yuck." If you can't get it out of the archives, let me know and
I can send it to you.
Cheers!
