    Re: Tinting Sailcloth?

    Paint is about the only answer for tinting Dacron sailcloth. It comes resin-coated and dye doesn't get in there well. My experiments showed that all I could get with dye was that it looked dirty when...

    Re: Getting rid of amine blush

    Yep, just plain water. Adding other chemicals to epoxy work is usually just asking for trouble, as well as being unnecessary in this case.

    Re: Getting rid of amine blush

    On a peel-ply surface the blush is still there - but it still floats to the top, which now is on the top of the peel-ply. Thus peeling the fabric off takes the blush with it, leaving a blush-free...

    Sorry, but the thickness of the coat is not what causes amine blush, and putting on thin coats won't prevent it.
