Hi All,
talking about to prime the cowling... i made some tests with grey primer on scrap cowling pieces. after one day of curing it was easy to scratch/remove the primer with my finger nails. now (a week later) i looked at the pieces again and it was much harder to remove the primer but i'm just not sure how well the primer should stick to the fiberglass.
so what is sufficient adhesion for you guys? is there any kind of measure or test to say when it's good enough?
thank you
Kay
