I have been reading these threads and just wanted to make sure I was on the same page as everyone else. I have been a aerospace composite guy for about half my life and was a little confused on some of the terms being used.
I have seen basically two terms used, wet and dry and was wanting to be sure the definitions. Seems dry has no shine and wet has a high shine.
In my background, we add peal ply to the outside of a layup in order for secondary bonding. Basically so we do not have to sand. (only in low G situations) because in composites, when it comes to bonding, if there is no shine, you will be fine. You can do this with either wet layups or prepreg. The look of this type of layup seems to be what you call "dry" and is ready to bond without sanding and has no shine
Your "wet" layups seem to be when you increase the resin on the outer layer, weither it be adding extra raw resin or a extra layer of pure resin prepreg to increase the gloss and to give a extra shine or it has been done in a zero loss closed mold and autoclaved. There is no proper name for this other than just laying up directly on the mold.
I guess the other question I would have is are the parts autoclaved, vacuum bagged or just layed up wet?
Just a little trivia for you, Burt Rutan did not believe in vacuum bagging when he designed the Long Ez. He got over it of course. heh heh
