Bob, that truly educates. Thank you. We did a high
pressure water wash in August. Stuff hung in there
about the same. But continues to flake off at it’s own
unsightly pace. If the substrait were Imron, and not
Awlgrip, would you expect the same answers from the
paint co.?
What I’m trying to do is get to the point I can touch
up the existing color, then protect the hull and buff.
So your thoughts about not abrading it are invaluable.
We’ll need to pry this patchy over-blight loose
somehow first, and uniformly. Sigh.

Imron is another story. DuPont makes that product and it is not as
glossy or as tough as Awlgrip. But, most painting procedures are
very similar. In order for that unknown clear to adhere, there must
be a scratch pattern for it to adhere which is mechanical adhesion vs
chemical adhesion. If the clear was of the same chemical consistancy
of the Awlgrip, it would adhere if applied shortly after the finish
coat had cured and could then bond. Then there would not be a
flaking problem.
Who knows what the clear was. Awlgrip does not need any more clear
to make it glossy.
Increase the pressure on the wash and that might work better.

This is probably offbase but I recall reading a review in Practical
Sailor recently of coatings in place of wax that last up to five
years. Not sure if flaking or just yellowing is the final
degradation. I do remember there was some indication of different
approaches needed for removal and applying new coats.
Just in case its relevant figured I’s mention it.
