Name That Brand

A lot has been said about RV tires and the spray protectants we all use, but with all the choices out there, which ones don't have the bad stuff in them? Can someone find out what is in them? What is the good one and why won't anyone name the brands? There are a lot in the stores. Bob M., (CA)

Bob, most all tire manufacturers say no to any protectant or additive that contains any petro-chemical. In fact, they say just keep the tires clean. The natural action of driving will keep the built-in protectants migrating to the surface; enough for adequate protection. The problem is, RVers rarely drive enough for those protectants to actually work as designed. 

If an aftermarket product doesn’t state all contents specifically on the label, one option is to contact the supplier and ask for an MSDS (Material Safety Data Sheet). Some MSDS documents are available online. The MSDS should indicate the specifics of that concoction. Personally I like 303 Protectant since it does not contain a petroleum product and it simply works. I quite looking after obtaining the 303, but I’m sure there has to be viable competition with comparable products out there somewhere. But as I often state, why change horses in mid-stream? I’ll stick with the 303.


In all instances, every effort is made to ensure the correctness of all content on the RV Doctor Website. It is imperative that if you choose to follow any instructions or procedures outlined on any page of this website, you must first satisfy yourself thoroughly that neither personal nor product safety will be compromised or jeopardized.
