:The Wurth product mentioned below is intended for door gaskets/weather stripping.
From their website:
"Restores and revitalizes rubber, rubber parts, bumper casings bodyside moldings.
Removes wax, buffing compounds, dirt and grime from new synthetic materials and enhances resilience."
It works very well!! Black Again does have it beat on price, I don't know about performance though.
