Just take the int panel off the door, everything comes apart very easily (faux c/f, map pocket, speaker grilles, lock plunger grommets, & door handles) from the back side...
Then just clean it up real good, shoot it with adhesion promoter, the color of your choosing, & a couple coats of flat clear...DONE!
I prefer a whorish spritz of RED personally...
I don't recall even having to mask anything off...
Brilliant, i can see you could be a sorce of very useful information...looking forward to a summer of modding and tinkering!..... Some great ideas on this site. Nice tonight
