No we are not talking bio-diesel
as you all know I have a second XJ a 99 sport I have been cleaning and tidying it up as it was a pig run
the plastic on the bumpers were grey door handles faded armorall was useless I know crc or rp7 will help black plastic but so so I rubbed all the blackish grey surfaces with used cooking oil looked greasy did the door handles as well let it cook in the sun for 4 or 5 hours then wiped buffed clean with a clean rag most had disappeared and like new slightly greasy for a few days but dries out a good soapy wash after 4 days and new BLACK!
