Lighting While Glassing

Does anybody have a good way to position lights that reveals dry spots in the glass? It seems there are always a few that slip no matter how many angles I look at it from.

…You need back lighting.Above(like on your ceiling or wall above your head) and in front or behind you(or both)length-wise,(above and behind(or in front) of you as you look down your board from nose to tail and visa-versa).This is a old auto-body trick,that I learned while working on Corvettes. …You’ll love it and hate it all in the same stroke!In other words,YOU’LL SEE EVERYTHING!Herb

Thanksalot Herb! My lights been overheaad but perpendicular to the board. I’ll try rotating 90o’s.Trevor
