Uses For 303 Aerospace Protectant?

I use it on the vent lid covers, tire dressing, all the rubber and plastic on the truck or trailer. I plan on doing the entire trailer roof with it.

Just like you use sunblock to go out into the sun to prevent sunburn and UV damage to your skin, look at 303 as sunblock for your RV and tow vehicle.

I use it all over our trailer's exterior. I do not wax our trailer any more. Wasted effort IMO. And I use it on all rubber and plastic parts inside and outside our tow vehicle, including tires.

Been using 303 for several years now, and I have found several thin coats are much better than thicker ones. Too, I have had better results with higher humidity temperatures, compared to higher, drier mountain climates, when it come to removing it.

Here in Texas, UV damage is our chief concern as our trailer sits uncovered plus car and truck interiors and exterior take a real beating due to extreme heat and UV damage.

Plastic trim pieces on the toad, slide out seals, in addition to the stuff above. If it's plastic/vinyl/rubber it gets wiped. :) :)

Where is the best source to get the 303?

I get it from Ebay.

I also use on the exterior of the TT. I apply it with a microfiber cloth. The most important thing to remember is it has to be put on sparingly. Too thick and it will streak when it rains. Put on correctly it looks fantastic and keeps the decals looking good. Not sure if this would workon aluminum sided trailer or not.

Use as protectant film in your RV shower. Makes cleaning the shower simple & very easy.

303 makes a special shower product different from the SPF for your stuff.

I use it like sunblock, it goes on everything.
Trailer, canoe, kayak, boat anything that sits out in the sun all day.

I spray the tires on my Southwind.

I use it everywhere most people use armorall and then a few others.)
