How do you know if you need the light or medium compound?

Thank you for your question! The 3M 36106 Perfect-It Gelcoat Medium Cutting Compound + Wax is formulated to remove moderate oxidation, weathering, dulling, and scratches as coarse as P1000 from gelcoat surfaces; leaving a high gloss wax finish. In contrast, the 3M 36110 Perfect-It Gelcoat Light Cutting Polish + Wax is designed to remove light to medium oxidation, swirl marks and scratches of P1500 or finer; leaving a smooth, high gloss wax finish. Oxidation of gelcoat surfaces can be assessed by the degree to which the white “chalk” transfers to the fingertip upon touch. Typically, light oxidation has virtually no transfer of the white “chalk” upon touch; whereas medium to moderate oxidation has partial/more substantial (although not heavy) transfer upon touch.

can you use on fiberglass tub?

I used it on a fiberglass boat and it worked great. I would think u should but I would ask a store that sells tubs.

Will this damage vinyl stickers (boat name & registration numbers)? Should I tape these areas off before buffing?

Thank you for your question! The 3M 36107 Perfect-It Gelcoat Medium Cutting Compound + Wax should not be put over any kind of decals, striping, vinyl stickers, etc.

What are the exact directions for using this product?

Wash very clean whatever you are working on (getcoat). Work in the shade defiantly. Tried in the sun, was tough to get off but came off. If possible use a buffer/polisher for ease. Pretty simple. I applied another gelcoat wax over. It works great on light to mid-medium jobs.
