Don’t forget to cover the part whit peal ply (or equivalent) before you lay the breather otherwise it will stick badly to the part.

I'm a bit "afraid" that I will get wrinkles on the surface if I put the breather on top of it, but naturally it's more important to get the excess-resin out. But will I get wrinkles? Yesterday I used peel-ply more than one lap around the piece and I just put the breather on the side and naturally nothing happened with the breather. I mean, I got the vacuum all right, but the resin was kept in the part. Should I just lay the breather on top of it, or should I wrap the piece one lap as I did with the peel-ply? I don't use a mould, but the piece is laying by it self in the vacuum-bag / Marcus Edited 13 Years Ago by brummelisa
