Tonight I tried
leatherique black leather/vinyl dye on my right door panel and it made it look brand new. The before and after is simply amazing!
For all you older boxster owners with black vinyl interiors, you gotta get some of this stuff and brush it on your vinyl. It dries in 24 hours and takes the sun faded look away and makes whatever you put it on look showroom fresh.
If anyone else has tried this before and has suggestions for me as to whether I should hit it with something to protect it (like a low gloss lacquer or something) that would be great.
...and I thought I was gonna have to replace the panel after the damage I did with 3M adhesive spray and that piece of leather I cut for it!
