Here's my process to laminate with rail wrap using carbon:
Mix a little epoxy and brush it on rails and a bit onto deck as much as fiber will wrap.
Lay out thick builders plastic on a table and lay dry cloth on it and wet it out with epoxy
Lift carbon and plastic onto board, flipping it on.
Smooth it out, peel off the plastic.
Using small amount of epoxy and squeegee pull cloth longitudinally from middle of the board.
Then from middle diagonally towards tip , do each side.
Snip cloth at corners and center of nose tail. Using hands ( nitrile gloves of course, using carbon filter gas mask), i wrap rails starting at nose , or tail from center.
Once tail, nose are wrapped, i work from center of longitudinal rail towards tip each side.
( I have tall glassing stands that has board at breast height making it easy to get to underside. Photo is on my shaping stands).
As I'm wrapping rail I might dip fingers in epoxy to lubricate so I don't pull fibers. I'm careful to not drag along fiber edge, I dab with fingers. I make sure wrap is sticking.
Note: by first mixing a small batch of epoxy and brushing on rail, epoxy has some time to absorb into blank and get a little tacky to act like glue.
Now I apply peelply, squeegee it out no wrinkles, then perf film.
Then I use masking tape to pull perf film tight. Masking tape sticks to perf film. Tape has to be long enough to reach around to dry blank or it won't stick.
Then absorber. Tape in place.
Then into vbag.
