303 Protectant and/ or wax

A friend of mine treated half his fiberglass roof with 303, and the other half with Protect-All. After six months he stated that 303 won the contest for durability. He treats the top to eliminate the white streaks bleeding down on the side of his coach. the half treated with the 303 was still holding up, but the protect-All treated half was bleeding white streaks on the sides.

I use Mark V wax with an orbital on the MH and 303 on the tires, dash and seats.

Tried an area on my rv with 303 and another spot with Protect All, the Protect All won the shine contest plus they go on and off in the same fashion. Protect All has UV protection plus Carnuba. I also use Protect All on the interior of my truck plus the exterior.
Protect All

I use the 303 on tires though

I have been using 303 aerospace on my camper for a year now. I really like the way it goes on and wipes off. I use a micro cloth to wipe on the 303, I then put the damp cloth in a zip loc bag till I need it again. I use another micro cloth or a towel to wipe it off. I found the best price on Cabela's web site.

havnt figured out what best yet nu finnish or rejex. roger on the 303, great stuff

I use #303 on my fiberglass and Nu Finish on my metal.

How do you apply it? Just spray it on and wipe it down?

I spray it on a buffing pad of a random orbital and buff it till it is dry, spreading it on an area about 4x4 feet.

I found this about 303 Aerospace Protectant

I have been using 303 since 1993. I do not wax anymore.
I haave found no reference to it being manufactured in China and the poster that stated it was could give me no reference to confirm his statement. My guess is he found a knock-off product using the same name.
