SEA GLOW™ Cleanser-Conditioner restores & maintains whiteness and suppleness while impregnating the vinyl with preservatives that protect against oxidation, yellowing and mildew.
Then...
SILKENSEAL™ seals the surface against weathering and water-borne grime.
Had the top been black or beige, NEUTRAL CLEAR™ would have been used instead of SEA GLOW™
The only precaution is to keep the Cleanser/Conditioner from contact with any glued areas. If this happens, immediately use water to inactivate the product.
These products are NOT FOR CLOTH type automobile tops.
