    I stripped,cleaned,and sprayed 2 coats of spi epoxy. On my schedule, it will take ,3-4 weeks to do filler work. Can I just scuff the epoxy anytime in that month window and apply filler? I read some posts on the subject and there seems to be some conflicting opinions.

    As long as its not out side in sun you can 180 by hand and apply filler, if outside you must recoat with epoxy.

    Barry, I have some windows in my shop that occasionally shine light on my epoxied panels. Does that affect it the same as being outdoors, or do the traditional rules (3-7 days) count?

    No UV's don't bend.

    After reading your reply, I googled and learned that apparently UVB rays don't go through normal glass, only UVA does. Not sure which cures paint more.

    I'm not sure you understood, or maybe I'm taking your response wrong. I'm not speaking of a reflection or anything, just light coming straight through a window onto a painted surface... no bending?

    I think a good way to think about it is, from the part can you directly see the sun in the sky? Straight line-of-site. Many windows are now coated to block UVA and UVB.

    When in doubt recoat it. The alternative could be a redo if you lose track of time.

    That window in the shop does not change anything also never have gotten a tan driving in a car.

    This makes more sense to me, it clicked in the head. If you had a skylight, you maybe would have an issue assuming the window wasn't coated to protect uva/uvb, but a side window is hardly ever in direct line with the sun.

    Barry, your last statement reminded me of a buddy. Always cruised around in high school with one arm out the window and at the end of summer had one arm that was twice as dark as the other!
