    How to restore black trim moldings?

    Whats the best way to restore the black trim moldings around the car? Mine is faded due to the FL sun. I just replaced the front bumper license piece and the it looks great. To bad all the other ones are old.
    thanks

    probably save money calling up a junkyard and getting the scrap pieces off a wrecked one..or paint them yourself.

    I took all mine off, then spray painted them black. It looks just like I treated them all the time. It also saves time when cleaning the car. I used to wash the car then take 15 minutes to treat all the black plastic. Now after i dry the car, im done.

    Did you use any special paint? Has it chipped? How long you been running with it that way? What was your painting process (sand, primer, sand, paint)?

    Sounds like a decent idea?

    There is a special type of paint to use, I have only seen it here at Canadian tire and its called black velvet or something close to that. I used on several VWs and it works great, flexable, doesnt flake off and leaves a nice finish.

    CIA, dinan chip, lowered on 18"s, red depo angel eyes, custom chrome grill (blingin'), vibrant exhaust...

    I do that too, but my moldings were never faded to start, so I don't know how much it has help.

    i currently use forever black too.. there was a thread on this stuff and everyone agreed this was the best stuff to restore the molding other than painting it. I'm now considering painting my moldings since I hate applying it every month or so. Im just not sure which paint to use. I'm afraid of it chipping off.. for those that painted it themselves... did you sand the moldings first or what? Did you apply a clear coat as well? What about primer? Thanks

    I had a similar experience with my shadowlining peeling off. I just stripped the trim and used flat black engine paint (because it's heat treated-direct exposure to sunlight) to repaint the trim. I'm sure the same will work for the moulding.

    I also used some of the same paint to paint the front part of the engine that's not covered by the plastic valve cover. It was also chipping. It looks great matched to the black covers.

    I had the same issue, being that my car spent it's whole life in florida before being transplanted to PA... I had one of those Mr. Clean magic erasers lying around and decided to see what it would do for restoring the moldings. It worked beautifully!!!! It took a little bit of elbow grease, but my 11 year old moldings look fantastic now. I used a bit of water for lubrication, but might work just as well without water.

    What im planning on doing...Is sanding the moldings down a little high grit sand paper. Spray one coat of black Auto trim paint, Let it dry. Spray another coat, and while its still sticky, add a coat of clear coat. let dry.

    ive heard wonderful things.

    the best longest lasting one is black shoe polish that comes in a bottle with the sponge applicator .. i've applied it and 8 months later still looks new .. even worked on high heat near the motor... try it .. its cheap too

    I just lightly sanded them, cleaned them really well and used black automotive trim spray paint. I chose not to clear coat it because i didnt want the trim shiny. Ive been running like this for the past 6 months, so i cant tell you how it hold up long term. So far so good

    last month i pulled off all my moldings, slathered them in meguiar's trim detailer (its a clear goop, not a dye) and let them sit overnight. in the morning, i washed them with dish soap & water, dried them off well, and put them back on.

    i wash my car once or twice a week and i havent done anything special to them since. they still look really good.

    Permant fix. Just did it and it looks brand new. No cover-up, no paint, no dressing every time you wash it to hide it.

    Put this in your tips and tricks book.

    Reviving, removing wax buffer burn and oxidization from your cars plastic textured trim.

    1. Rub surface with pink pencil eraser (.99 cents for a 2 pack at target)
    2. Dust off eraser mess.
    3. Spray with a strong degreaser.
    4. Wipe/buff with a Magic Eraser and water.

    The oxidization/wax is gone. Looks brand new and saved me well over 300 bucks.

    All the "Restore" products do not work long term. Grease, magic erasers, blah blah. Temporary bullshit.

    Do the thing right and purchase SEM Trim Black spray paint. This is OEM quality black trim used by body shops to restore plastic components.

    I have used this product to response my Hummer h3 plastic a year ago and it looks brand new still. I have used it on my e28 to restore plastic twice (second time because i was in process of painting the car and didn't mask stuff off).

    Did mine with Plasti-Dip 3 years ago now, still looking mint and zero maintenance.

    Also did the metal strip that runs from the bottom of the A pillar across the top of the windows.
