I got my fifth wheel all washed up today, including the roof and added a cost of wax to the front cap. I used the aero 303 on all my decals and was wondering if anyone uses this on the roof vents like my max air and the plastic toilet vents.... The directions say good on plastic and just about anything.

I have put it on mine. I use it on my boat as well. Good stuff !

I use it on everything except the glass, from the ACs to the tires.

It can be used on a lot of materials. I always spray my tires.

Great stuff ,use it for about anything I want to shine up a bit ,and protect. It works great on my inflatable pontoon boats, they take a beating in sun, and water.

I do the entire roof including vent covers, AC cover, fridge vent, etc. Basically everything up there. A sponge type mop works well for spreading it around on the rubber roof.I'm not aware of anything that is considered "unsafe" to apply it to.

We order on line from camping world!!
Use it on all the slide seals. Just don't use it where you walk or step. It is slippery.

303 goes on easy and easy to wipe to a shine but after using it a few time it doesn't last long (1-2 washings) especially on a front cap.
I like something more heavy duty that lasts a couple of years and several washings.

Never used it on gelcoat. For that a top marine sealer is needed to last any more than a few months.

303 freshens up the plastic graphics pretty good.

Most marine stores. Google their site for retailers. Seems to be hit & miss depending on region as far as distribution goes. See it when
I don't need it. Can't find it when I do.

Bought a gallon from www.defender.com That should keep me happy for awhile.

303 also makes a fabric protectant that is recommended by Sunbrella for their awnings and covers...I used it on my boat mooring cover for years and it still looked like a new cover.

I also use it on my leather seats in my F350

Great stuff!

I met a couple with their high end coach and he said 303 is the only thing you should use on tires as it is the only non petroleum product. If it good enough for a million dollar coach it is what I am going to use!
