I'll use 1708 tape to tab in with and then just use 17oz biaxial as it drapes nicely and don't have to deal with the chopped hairs that tend to pull out on subsequent layers. I find that regular 1708 cloth tends to fall apart, but maybe I just work it too much.

I also use "plain" biax tape quite often (no mat). Agree it's pleasant to work with. I like the Episize 4" quite a bit (if one can "like" fiberglass )

. Sometimes that is a nice feature. Even on the worst day, 1708 is way less messy than regular mat. I had a task patching 18 smaller holes in a panel a month ago and i just cut a bunch of patches, ruffled them a little to make them less defined. Then i just stick them to the side of the mixing cup and pick them up with a brush a patch at a time. Never touched anything with my hands. Not sure these images works. This was not Structural but 2-3 layer biax capped the hole underneath. I had a 1:2-1:4 bevel on top, filled with hull and deck putty using a syringe and then gelcoat. That beige albin color was hard to match starting with white gelcoat….

Hopefully these dropbox images comes through

Trying,, sorry for the last one being upside down. The take home is reallt the awesomeness of 1708 allowing you to work without looking like a chia pet :-). I would start with up to a dozen patches on the wall of the cup and wet them all out in the cup before putting them in place using the brush. That way i’m not getting resin everywhere either.

Peel ply is very cheap. You only use it on the last layer in a wet layup. It will hold the edges and all the fuzz down so that when peeled off the patch is smooth. Often if carefully done, this eliminates the need for any finishing, but in any case makes finishing or subsequent layers easier and better. Not sure how it works with polyester.
