Gelcoats are flexible polymers sprayed onto composite materials such as those that are used on boats and bathroom furniture.
The coatings are polished to provide a high quality finish and extra protection.
The gelcoats can be polished at the original application but also during refurbishment and restoration.
A typical sequence would be to sand using Dual Action or Orbital sanders from 600 grit up to 1000 or 1200 grit, then use Gelcoat Cut and Polish with a lambswool bonnet followed by Gelcoat Gloss with a lambswool bonnet.
