Spray-On Protection Bra
A Spray-On Protection Bra That Won't Fly Off, And Is Easy To Remove!
When I first tested this product, I was skeptical. By now you know that
I'm VERY finicky about my paint. So spraying a protective coating on the
front of a Porsche would be silly, right? And when I was done with my
road trip, having it peel up in one big sheet would be too easy to remove,
right? Hard to believe, but that's exactly what it did with minimal fuss. I
even applied the Protective Bra over the hood ornament! Finally an easy
way to protect any surface from rock chips, abrasion, sand pitting, bug
residue, etc. Other uses would include: inside an aluminum boat for a
non-slip surface, aluminum stair treads, tool boxes, instant drawer liner,
truck bed liners, car door thresholds (where your shoes scuff the paint),
and on the back of hatches and trunks so you don't scratch the bumper
or trunk lip. Water, oil, solvent and impact resistant. One can covers
approximately 12 sq. ft. $12.99 a can.
