As in polypropylene, polyethylene, etc.

Does anyone use any kind of protectant on their Pat's interior?

I've used 303 Aerospace Protectant for years on my interiors and love it. Low gloss, just clean. Kinda stinky, though as my wife hates when I uses it on her vehicles.

Edit: Wow, there were some bad typos.

Interesting...not silicone like most products.

Meguires Dash foam here. I think it has a nice "new car" aroma and it adds a slight bit of gloss without making the entire dash feel slippery.

Yes, I don't want slippery or sticky...but also want something to protect the plastic from long term sunlight dammage. That 303 stuff advertizes itself as a UV protectant.

We actually went with a dash cover to handle the UV damage, but its probably alot worse here than where you are. There are a ton of companies around (mopar didn't have it when I was looking to use my coupon last july, but probably by now...). IF you go this route, the only thing is - see if you can get swatches. The company we went with didn't have the exact color we needed and its more noticable than I thought when ordering, but too little time (or just laziness) to send it back.
