For use with any resin system and reinforcement combination, a great way to speed up the lay-up of large structures and ensures even coverage.Gel-coats and resins can be applied by pouring into the moulding and spreading through with the roller or for best results, use a paint tray and apply from the roller.After use rinse the roller in an acetone bucket and leave it submersed until the next use, ensure that the acetone is thoroughly shaken out before each use this is especially important for gel-coat application. If cleaned properly a roller can last many months of daily use. Bristle Roller Refills - rollers only without the handle are available separately.
