Hi Larry,

As I understood their instructions, you have "up to 72 hours BETWEEN each coat". Longer than that, and you may see some amine blush. In other words, as long as the coats are on within 3 days you should be blush free.

When I glassed my Arctic Tern, I know I went at least a couple of days between one or two of the coats and had no problems. Worst case, I think you'd see the blush and could simply wash it off.

: Just getting ready to glass the hull on a Pygmy and wanted to know if, after
: saturation, the fill coats need to be applied every 24 hours. Will waiting
: longer mess thing up later? Using Sys III epoxy and they say 72 hours
: without sanding. Does this apply to the fill coats as well?
