Default Rubber restoration

I have an old [new] trunk rubber gasket for a 36 trunk back trunk. It has minor damage with small indentations. Anyway to restore rubber seals , I would like to use this one if possible. Thanks 36 CS.

Hi CS,,
an old school trick used in long days gone by,, to restore/freshen up old perished rubbers and hardness was to bring to a boil a pot of water with added amount(s) of vaseline., turn down the temp then immerse the rubber and turn up again to a small simmer for a period till you determine if good for you and then turn off the heat and let sit till cooled off.

This process would soften up the old rubbers and bring back some life to them, and somewhat allow the rubber to retain its elasticity.
It possibly could get rid of those indents you have in the rubber..
What have you got to loose,, you wont damage the rubber and vaseline is cheap

Flood the part with Silicone Spray. It will revitalize the rubber to as good a condition as possible

I have repaired a lot of windshield rubber with a product called sikaflex. It's a one part polyurethane adhesive sealant. It comes in a caulking tube and is very common in boat building and repair. I clean where I want to fill with lacquer thinner then apply it with a custom shaped spreader cut from a tupperware lid, or if you're married, a plastic coffee can top. You would want the 241 product and make sure it's black because it comes in a few other colors.

Soak it in bleach. The longer the soak, the softer it gets.

When I stored my rubber hip-boots after duck hunting season I would always wipe them with DOT 3 brake fluid to preserve the rubber. I think DOT 5 would work even better....

Wouldn't that tend to contaminate the duck pond the next time you go duck-shootin'? DD
