The function of 202 Fiberglass Solvent Wash is very similar to Interlux Fiberglass Surface Prep; see Related Products, below.
The main difference is that Fiberglass Surface Prep is a low VOC formulation (only 3% of the VOCs compared to 202 Solvent Wash), which utilizes weaker solvents and therefore requires more work to use.
So, if you require or desire a low VOC product, use Fiberglass Surface Prep. But, if you have protection from VOCs, wipe on/wipe off 202 Solvent Wash is the product of choice.
202 Interlux® Fiberglass Solvent Wash is used to remove mold and to release agents, wax, oil and grease from the hulls of bare fiberglass boats in preparation for painting.
202 Solvent Wash is a combination of several solvents, some of which are very slow to evaporate from the gelcoat surface being wiped. This characteristic is very important because any wax contaminants must stay in solution so that they can be wiped from the surface before the solvent dries.
202 Solvent wash is also an excellent parts clean-up, paint brush cleaner, and multi-purpose wipe down solvent.
