Guys, on glassing the engine box, I went a different route. Aircraft Spruce sell carbon fiber cloth, in different weights, not terribly expensive. I cut approx. 4" wide strips, the length varies on the seam I am covering. Goop the area the fiber covers with 10-15 min epoxy, lay the fiber over the glue, brush a little to spread it where you want it, cover with wax paper, take a 2x2 alum angle, (helps to be a custom steel fabricator) and clamp. When you are done its very clean, and rock solid.
