Can be used above or below the waterline; approximately half the strength of 3M's 5200, which allows for eventual dissasembly of parts. Note: Can be softened by some teak cleaners and sealers and is not recommended for sealing teak decks.

Comments about Fast Cure 4200 Polyurethane Adhesive/Sealant:
4200 is a thick product that bonds tenaciously to a wide range of surfaces. Unlike 5200, it allows bonded parts to be removed at a later date with less risk of damage to gelcoated surfaces.
Good for use under the waterline to seal thru-hull fittings and under water light housings.
The product is difficult to clean up, which is a trade-off for the superior bonding characteristics.
White 4200 yellows somewhat over time, so do not use it in high visability areas, such as windshield frames and trim areas. Use 4000 UV in those situations which will stay bright white.
