One more question. When you do peel ply, do you use a breather
absorber material or do you just absorb the excess with a roller?


Neither.

I used a layer of very cheap PVC sheeting (sold in Home Depot/Lowes as
painters drop cloth), which will not adhere to resin, directly over
the peel ply. Lay on the goop, lay on the FG cloth, lay on the peel
ply, lay on the drop cloth; then roller the crap out of it (being
somewhat careful to not wrinkle or tear the sheet... easy when one
gets the knack); then go do something else for a few hours. With the
plastic sheet over the lamination, bubbles don't tend to creep back in
once the stuff is rollered down good, excess oozes thru the peel ply
and off the edge (in fact I often scooped it up and used it
eleswhere). The peel ply can't be re-used but the PVC drop cloth can
be used many times. Get 3 mil for large flattish areas you want really
smooth and rollered down hard; use lighter stuff down to 0.7mil for
compound tight curves and be gentler with it.

It's not quite as strong & light as vacuum bagging, but it's cheaper &
simpler & quite reliable.

I'm not sure burlap would make a good breather. You want something
that will be relatively transparent so you can see the bubbles & work
them out. A thin layer of matte, such as would be used to vacuum bag,
would probably work but it's one more specialty item to buy.
