    hey guys.

    i've heard a wee rumor that if you get a heat gun or even a hair dryer on the plastic bumper bits it'll turn them from grey to black again! how true is this as i've got a couple of grey bits on mine. or is it eayer to use some matt black paint i have laying about lol.

    thanks.

    Heat gun works a treat! Don't be scared, just be careful when working near painted plastics as it doesn't take much to damage the paint.

    Try it, you will be pleasantly surprised :)

    I used a heat gun on my MK2. It worked but they don't stay black for long.
    Also I had to get them really hot, you are melting the top surface so it turns black. I don't think a hair dryer would get hot enough.

    That's a fair point actually Mat, noticed my rear bumper had gone a bit grey again on Sunday :(

    Don't know what product to use though as everything seems to stain the white paint on my car. I try not to get any on but it's inevitable unless I mask up the whole car (massive blag)

    Heat gun or blowtorch on a low flame, and be very careful if you use a blowtorch. I use a piece of sheet ally as a heat shield to protect nearby paint.

    Quite a few vids on YouTube to give you some ideas......it has Worked on mine, but the car lives in a garage out of the sun doesn't really get wet.... Really don't think there is a permenant solution to having to use elbow grease occassionally

    Kiwi - black shoe scuff cover, the one in the bottle with sponge applicator. one coat on a bumper will last around 3mths

    Is that the one that comes in a bottle with a sponge on the end? Would it not come off on your clothes if you walked past it?

    kiwi is what i used on my driver, lasted for ages. if you never clean the car it lasts longer :thumbup:
    it wont come off if you brush against it, but if you lean on it you can damage the finish. i had a few jean marks on my bumper from engien work :lol:

    i did the bonnet grille leaf tray thingy on my gti in 2003 and its still black, though a little scratched in palces from where ive pulled leaves out of it

    Another vote for boiled linseed oil :thumbup: Did it in september, a whole winter of scraping snow and ice off the bumpers later, and they're still looking good. Has lasted a lot longer than the heat gun treatment did.

    Although might be worth trying heat gun then linseed oil?

    well i was thinking gloss so massive amounts of **** elbow work in sanding the plastic down and all that crap. making it look standard but newer sounds more practical.
