Opey,

Are you...

1. Using a new razor blade
2. Holding the blade correctly
3. Using old or incompatible resins
4. Using good batteries and bulb in the UV lamp
5. Using cure tabs when curing
6. Using pressure when appling the cure tab
7. Using sufficient resin
8. Noticing this after you polish

Just a few things to consider.

Pay it foward,

Brian
