I just went through a fairly extensive blister repair and basically if

Please excuse my ignorance. Are polyester and epoxy the same thing?
Also, you say 'assuming the hull is polyester', do you mean as opposed
to wood, steel or aluminium?

OK, maybe I should know some of this stuff, especially as my boat is FG,
but are there different resins used to bond FG? If so, when carrying out
repairs should one stick to the same type or does it not matter once
it's all hardened?

There are a couple of dings on some corners (yes, I did both of them,
but I'm getting better), I say corners, but they're hard edges, not
curves, one at the bow, and one where the transom joints the port side.
Both of these parts have already been coated with what looks like paint
- it has brush-strokes, unlike the rest of the hull - and the strip
extends about an inch onto each surface. It's possible a previous owner
tidied up similar knocks the same way... anyway, I'd like to repair
those dings as they aren't attractive and are a constant reminder of
abuse I'd like to put behind me. I'll have a look at the West site, but
I want to be sure of the answers to my two questions before I tackle
these.

Interesting reading so far, and thank you for any help you can give with
my questions.

Epoxy and Polyester are different things. Polyester is generally used
for laminating like building your FG boat, Epoxy has more adhesive
properties and is used for types of construction other than laminating.
Epoxy can be used for laminating but it would be expensive and the
process would be tedious.

Rather than go through it all again, look back just about a week for
Tim's thread on the exact same subject. It is full of everything you are
looking for here.
