it doesnt take much heat to cure smooth on when using it on overlays. Make sure you dont put light bulbs too close to the bow..you can over heat the glass and epoxy and warp limbs..Like Mike, I use the clamp on work lights,I have the small ones only rated for 75watt bulbs...I use a 75 watt bulb and put it at least 14 inches from bow, my shop is heated so it already warm. On The last 2 bows I used Super Glue for tips, I used the Gorrila Glue brand of super glue with rubber, got it at Walmart..I think smooth on is the best but others have used the GG super glue and liked it,so I thought I would give it a try.
