looking down the length of my north bay i can see vertical lines from squeeging too hard,only visible when viewing from a 5degree angle(where's that protracter?) otherwise are you talking about wavy lumps where the glass could have floated a bit on excess resin? split the differences and don't worry,sand until some glass gets scratched,coat with resin,sand again,don't worry and varnish, varnish won't fill that much
