thanks for the comments and suggestions guys. as to the amount of gas
we burned that night, Bob K might know, it was in his shop where we
layed up the skins.............

I am leaning now towards JJ's suggestion and not go with the Prestec.
I have pretty crude painting facilities at my shop (read none) so I
hope the PPG products can tolerate a less than ideal spraying
environment.

when I sanded down the second fuselage half, I noticed that the
gelcoat on that side was a bit more tenacious that the first side,
sorta had me wondering if I could leave some on and just prime over
it, but despite have sore arms, I bit the bullet and sanded it all
off..............well, that's the plan, there is still alittle bit
left to do.

my hat is off to all those brave folks who have done
this..............it is not fun!

Brad

PS............Bob L..........we are going to make some wings in the
next month or so at Bob's shop...........what can we do to prevent
another disaster like this!!!

Brad – There are several issues that are potential problems: *As has
been pointed out there could be a moisture issue, or a moisture +
combustion by-product contamination problem. Another contributor to
gel coat adhesion is the timing of the cure and laminate application.
It is not recommended to allow gel coat to cure overnight before
applying the laminate. The window for maximum adhesion (with properly
cured gel coat) is 45-minutes to 3-hours. If the temp was high enough
during the overnight period, the advanced state-of-cure of the gel
coat may have resulted in a less than optimum interface bond. The last
potential concern is the use of micro (or any other filler) in the
resin. This reduces the wetting capability of the resin and again
reduces the interface bond strength. I’m guessing you had all these
factors leaning in the wrong direction.
