Hi all... my first post here

 

I just bought a 95 Cooper SPI and there are a few spots or surface rust on the sill lips and under the boot rubber. 

I am going to repair the rust and respray then add a new rubber boot seal and possible a rubber side sill.

 

My question is: should I add grease or Vaseline underneath the rubber to add an element of waterproofing to help prevent future rust? 

 

Thanks

Grease and I'm sure Vaseline are petroleum based and will rot ordinary rubbers, like these.

Yup as Spider says its best not to use any product that will rot seals.

Personally I'd just not fit the sill strips or fit them so you can remove them to clean.

Thanks for the replies. I will fit the boot rubber dry and have a think about the sill trims.

I did think the sill trim would help prevent rust in the future, but is it in fact better to leave them without?

 

One more rubber trim I am considering is the one for the rain gutter on the scuttle panel... is this recommended at all?  

Grease and I'm sure Vaseline are petroleum based and will rot ordinary rubbers, like these.

Use some dry PTFE spray.
