Do I have to take special procedures to
bond with Hysol or epoxy resin on polyester parts?
Just sand off all the gelcoat and prepare as you normally would. I
used Hysol and put 2 BID over the joint on the inside and on the
outside.
Removing all that primer coat represents a
lot of sanding ours and a lot of dust. The coat is so deep in the fiber that I
have found two situations: or I do not remove all the coat or I will damage
the fiber. Both alternatives are not acceptable. Suggestions and
ideas, please.
I sanded all the gelcoat off my cowl using 36 grit and a disk sander. I
have noticed many LNC2s with cracks in the paint on their cowlings. I think it
is the gelcoat that cracks when exposed to heat cycling and vibration. I would
suggest sanding all the gelcoat off. It is a lot of work, but it's worth it to
prevent the cracking. Where you bond, you have to get it all off. Everywhere
else, just sand until 90 to 95% of it is gone.
