Epoxy resin and eliminating bubbles
I've tried nearly every combination imaginable and still get these consarned bubbles! I've even done a fairly decent search here (even via Google), and haven't read anything very convincing that's different than what I've already tried. I'm beginning to think it might just be a temperature issue (it is getting into the upper 80's here by late morning). I'm mixing West System resin with both speeds of hardner (slow and fast), and no matter which additives I stir in, I still get them. The best method I've seen so far is to limit the thickness, but then if you are filling a large gap using fairing compound, then what's the point. Is there a trick to eliminating bubbles? So far, I'm finding myself going back 3 or 4 times, sanding and filling, sanding and filling... There's gotta be a quicker way, but I'm not discovering it on my own... puzzling.
Any ideas would be most welcome-
