A premium quality liquid cutting compound for use on all types of marine gelcoats and paintwork which are in poor or oxidised condition and need revitalising. Fibreglass Buffing Compound uses a unique blend of amorphous silica abrasives which provide a quick initial cutting of the surface, and then breaks down into smaller particles to polish the surface. This results in quick removal of surface imperfections and removes any swirl marks created while cutting to produce a smooth surface ready for polishing to a high gloss final finish.
