Archived from groups: rec>boats>building (more info?)

The sun has given my fibreglass top a white bloom. If I buff an area very
heavily with a mechanical polisher and T-Cut and then polish it comes up
nicely. Trouble is, it's taking far too long as the gel coat seems to be
much harder than the paint finishes that the T-cut and polish are meant for.
Anyone know of better products / methods to get the shine back more quickly?
TIA, Pete.

We use 3M's Super Duty Compound with a high speed buffer. Then we
apply Mcguires Flag ship wax with a orbital buffer. It works very well.

A different approach is to clean the gel coat with Comet, using a
stiff-bristled brush, rinse, dry and then apply Penetrol, a paint-flow
additive. The results are amazing. If you want to spend a little more, buy
Marine Penetrol, but I couldn't detect any difference in the results. The
shine will fade, eventually, and a yearly recoating may be needed. I have
found this to be a really low-cost, rapid method for treating badly oxidized
gel coats. Google returns pages of information on the product and its uses.
