RE: Fiberglass cowls........
Thanks manks,
I've already started putting a 2nd layer into newly purchased ARFs' cowls. It works a whole lot better to do it right away. I clean the inside out with denatured alcohol and acetone and have used 2oz cloth and epoxy on the 46size I'm partial to.
BTW, polyester resin won't always bond to epoxy. Truth is, I doubt the ARF mfg's are laying up epoxy since polyester is usually cheaper. And it's usually measurably stronger to layup all the layers at one time. So I figure my reinforcing could be better done by the worker making the part. Just personal preference.... I'm sure my reinforcing is adding enough strength, it's just that it's also excess weight for that strength.
And it'd also be nice if this issue got loud enough that word somehow got back to the Chinese that their glasswork is hurting their sales and they'd improve it.
