View Full Version : Peel Ply - warning

A while back a string talked about using peel ply for a number of things in boat building and many folks highly reccomended it.

So always looking to try something new, I got a roll and used it on this years project.

The results are/were mixed.

When used on the edges of the wet glass it was great, feathered edges with no sanding.

And when used over thin glass that had too much resin applied, fair results.

And put on glass that had a reasonable amount of reason, bad news.

The bad - the peel ply did it's job and sucked resin from the glass, resulting in resin starved areas. On the light/tight weave glass, 2.3 oz, it wasn't too bad, just a "few" starved pockets. But on the thick/looser weave glass, 2.85 oz, that had a just a little too much resin, many areas of starved glass.

The message, be very carefull where you apply peel ply.

Thanks for the warning. I have a feeling peelply is designed for thicker laminates that have a tendency to get resin rich. I am considering using it for my project. Seems prudent to have a dummy run on a test sample and not be stingy with the epoxy.

I can generally see the substrate through the peelply and whether i've gotten saturation of the glass. If it still looks white, keep squeegeeing the resin around. I use the yellow plastic spreaders. (6" size is about $.30 per).
