## Customer Reviews

### ⭐⭐⭐⭐⭐ A must for a fiberglass job.
*by I***O on October 25, 2025*

Works as it should.

### ⭐⭐⭐⭐ Worked as expected
*by D***I on October 28, 2023*

Added to gel coat to minimize tacky surface on final coat.

### ⭐ jar lid loose, packed in paper instead of sealed plastic, smelling of organic solvent
*by N***N on July 20, 2022*

The jar lid was loose, and the jar was improperly packed in crumpled paper instead of sealed in plastic, as would be any liquid shipped correctly, let alone a toxic compound. The box smelled strongly of organic solvent, suggesting some of the contents had sloshed out into the packing paper, or simply vaporized. Due to chemical sensitivities, I use a respirator mask with carbon cartridges when working with polyester resin, but was unprepared for the solvent exposure from opening a small paper box, as I fully expected the toxic contents to be responsibly packed for shipping.
