Greetings:

While I have my rear frame support rubber cushions out, I noticed some cracking in them – It appears to be minor and the following picture is probably the worst of them:

Any suggested treatments to prevent further cracking and to preserve them? – Net search came up with LOTS of ideas, but thought I’d try here to see what others have done to our specific parts.

Thanks for the input!

The 303 aerospace protectant gets excellent reviews. I remember Toby M says it is recommended by RV manufacturers for the rubber slide components. I am planning to use it for my airbags.

If they haven't collapsed or started to crumble put them back in for another 30 or so years or when they fail. Whichever comes first.
