Star Brite Premium Marine Polish with PTEF is simply the best polish you can buy. The PTEF polymers provide unmatched protection against UV rays, seal the surface to repel stains and deliver a deep, long-lasting gloss. Application is simple, whether by hand or with a buffer; apply, let dry to a haze and wipe off. Use once per year to keep new and restored boats looking their best. Ideal for all fiberglass, metal, glass or painted surfaces. Note: if surface is oxidized or hazy, use One Step Heavy Duty Cleaner Wax with PTEF.
