Hey guys - I know this has been covered before, but i've forgotten the answer. I'm currently solar-bleaching a set of decals in a window, stored in a Zip-Loc and taped up. The decals aren't too bad, the varnish is yellowed, but I've seen worse. Generally speaking, about how long in bright sunshine should the decals sit before their ready? Or is the answer "until the're done" the only answer? It's been a couple of days and there doesn't seem to have been much change. Thanks for your help.
