Hard Shell Car Wax
Promises: Hard shell lasting up to 12 months
We don’t ordinarily fear using auto wax on boats, but a neutral color or no dye in the wax would be a smarter choice for Turtle Wax, even if that’s inconsistent with its marketing mechanisms, i.e. green like a turtle.
Results: Its high luster saved it from the dismally low score it should have gotten. It tinted the white gelcoat green, completely negating the cost/shine benefit factor by doing so.
Pure Oceans NanoTec
Fiberglass Polish with PTFE
Promises: Biodegradable; superior protection; citrus scent
Not a cleaner wax, the citrus base of the wax is reported to be more environmentally friendly than petroleum bases. We could not verify that claim.
Results: Its citrus odor made it pleasant to work with. It was the thickest, creamiest liquid wax we tested and so easy to get just where we wanted it. Its value price (fourth in cost factor) and shine gave it a high overall score.
Promises: No rubbing or buffing; nonslick wax finish — even blood hoses off
This petroleum-based “wax” has an oily character. It is advertised to work on fiberglass and to be particularly beneficial to nonskid decking. Application is to wipe on and to not wipe off.
Results: Its high cost and low luster lowered its score significantly. It also stained the gelcoat an oily brown — exactly the color of the compound. There was no discoloration of metal, and we recommend this product for protecting aluminum marine structures.
