Hello,
I'm getting ready to
repair rust on my Mac 25
keel, I went ahead and purchased Pettit "Rustlok" and "Tie Coat" for the prepping which after some
research looks like a good choice. But I have a fairly large pit to fill and fair about 10" x 5" and 3/16" deep. My question is how should I deal with that? My plan was to first hit it with two or three coats of the Rustlok, then use epoxy/filler over that - fairing and
sanding smooth then proceed with coating the entire
keel with Rustlok (two or three coats) - hit it with tie coat (two or three or four times) then top coat with Pettit ablative
bottom paint. My fear is the
epoxy won't adhere to the Rustlok as well as bare metal so should I do that first? I don't have the option of sandblasting and will be coating over some rust.
