Remove them from your panel first(rear quarter trim comes off door panels do not). Then scrubbed several times with a brush and dawn dish soap. From there I used a sharp blade and cut all top layer off. This is the yellowing plastic layer thats lifting, remove the chrome layer which is like a foil tape. Remove all the loose pieces and scrub again. Once its dry paint to your desired color combo. I used a matte metallic silver for the outer trim and a gun metal grey for the basket weave. You might be able to use a chrome type pain to replicate the original but make sure you test it out first.
Keep in mind this wont satisfy original type guys but Im very happy how it tuned out overall. Its held up good too so I do think its a great alternative to save the parts you already have and give them new life.
I had the Dark Red SEM custom eye matched at my local automotive paint supply store. The manager did a great job eye matching the color. There was an upcharge to eye match the color.
Which SEM Clear did you use? There looks to be few choices.
I am in the process (we’ll have been for a while) of accumulating odds and ends for my oh so easy to find Nugget Gold Interior. No longer able to find SEM gold but I found some OER from Classic Industries that ‘appears’ close.
SEM low-luster, Satin, or high gloss? Which is more-gooder?
