Whenever the slide is moved out on my 1999 Designer 2930, it yanks the gasket off along the whole top edge. The metal teeth are all rusted inside the gasket channel and it covers the slideout top with rust when the gasket pulls off.
I'm thinking it's time for a replacement. Is this a universal or very common type gasket carried in bulk somewhere or is it model specific? Any good online sources?
Once the new one is located and installed, I found some threads saying to treat it with 303 to keep it slick & pliable. I just happen to have a gallon of that laying around. Here are a couple that I found with a quick search:
As a side note, the rails were kinda rusty. I figured they should be lubed so I painted them up with Fluid Film. Any harm in that?
