Hello, I have a black V50 and wanted to start the full washing program with Kneten and a stronger polish ( Ultimate Compound ) on the weekend time, because I wanted to remove the whole wash lane swirls from the predecessor. I tried it already with paint cleaner and Meguiars Scratch X. Since both did not work something stronger must. Since a Uni Lack has no clear varnish over it, I wanted to make sure that there is not too much paint down there. With hand polish anyway not so much down, but is sure … I found on this page:http://www.mobilverzeichnis.de/volvo_farbcodes.htm the following information: FIRST. NAME CODE BUILD YEAR LACK VOLVO BLACK PEARL 429 1995 METALLIC VOLVO BL. SAPHIRE PEARL 452 2000 METALLIC VOLVO BLACK 346 2001 can be found here.
