Re: [bolger] Ready to Raka Roll!
David,
First question: You just wait until the applied coat of resin feels
tacky to the touch but no longer leaves residue sticking to your
finger or glove, and then mix and apply the next coat. This is how
it works with West and Mas epoxies. I have no personal
experience with Raka products, but the chemistry should be the
same.
Second question: I usually try to turn the hull so that I'm working
on a more or less horizontal surface when applying the glass. It is
indeed a good idea to conceal the glass butt on the bottom if it can
be so arranged, if only because it saves you additional work sanding
and filling to a yacht finish. You don't have to do the bottom first to
accomplish this, just fit the glass for the sides so it goes over the
chine and onto the bottom. the glass fabric is flexible enough to do
that that if you've rounded the chine nicely. There is something to
be said for glassing one side on the horizontal, turning the boat
completely upside down and glassing the bottom, then (as the epoxy
on the first side will have started going off and will tolerate some
abuse) turning the boat so that the second side is up and horizontal,
and glass that side. Put clean plastic sheeting or wax paper onto the
staging where it contacts the coated hull to avoid gluing the whole
works together at this point. After this final side is done you can turn
the hull bottom up and proceed with the subsequent coats of epoxy.
As these are thinner and the glass is now wetted out, your work is
much less likely to sag and run, so the boat will require no further
positioning.
I know this all sounds like a complicated process, but I've found it
actually makes the process easier *if* the hull is reasonably easy to
turn with the help on hand,
YIBB,

West's Epoxy works came yesterday and they tried a lot of primers that all
worked pretty well on dry epoxy the only one I remember is Bullseye.
Don't buy paint from Home Depot go to a paint store and buy some decent
paint and a little service to go with it. The stuff the discount houses
sell is pretty poor quality compared to brand name paints. For a boat you
aren't talking about 10 bucks difference. It's not like epoxy where they
are all using the same raw materials.

100% acrylic exterior house paint is supposed to go over epoxy very well,
without any primer. Be sure to scrub with brilo pads and mild soapy water.
Everybody, including me, likes porch paint because it's a tough paint, and
they don't want scratches and whatnot on thier boat. Without primer, it
comes off in sheets. When you use primer it sticks well enough, but when you
do get a scratch, the paint pulls away from the primer coat (sticks fine,
but is harder than the primer, small flakes will separate from the primer
where you scratch it)....
Oil based primer doesn't cure well, use water based.
I personaly haven't tried the 100% acrylic latex exterior route, but some
people swear by it.

This doesn't sound good at all. I didn't even need three coat of
paint (and no primer,) on my polyester boat.
Anyone other paint ideas that can be found at Home Despot for covering epoxy?
