Question is using "303" on the inside vinyl surfaces. An assumption that UV degrades plastics/rubber/vinyl is a valid one; but, how much UV can penetrate the window screens or clear plastic flaps on the FWC? I suspect darn little and what does is diffused and of little significance in damaging vinyl or plastic inside the camper.2020 said:Does anyone use 303 protectant inside? If it treats the vinyl to prevent drying & cracking then it might be prudent. Some UV gets in through the windows, too. Or would it be overkill?

I use it inside and out on the liner. Make sure you get the right one as there are several other products from this company but only this one for our liner material.

Thanks,

I do use it on both sides.
Usually before and after a big trip and when the camper is out of use for the winter.
But it wouldn't hurt to use it on the thermal liner,same material.
