hi, im planning to coat ma VW golf MK3 front and back bumpers with a coat of matin silver (the color of my car)... i jus need some advice on how to sand it down so the bumper is not all bumpy when i spray it down. Does anybody know how to do this and what kind of sanding material i should use?
Also anyone know of any garages anywhere but preferably in london dat does customised work ? (for example:Exhaust, tinted windows):undecided:

Hi.. plastic bumpers require specialist products, and knowledge for a succesful job, best bet would be to get a decent bodyshop to do it for you!
If you really want to do it yourself, try this way, assuming that you are using aerosols..
and the bumper is "OFF" the car
wash the bumper with a strong detergent solution, and "Key" the area that you want to paintwith a peice of grey scotchbright abrasive pad, DO NOT use any type of rubbing paper, as this will rip the plastic to shreds!
Prime the bumper with the correct primer for the type of plastic (most bumpers are made from ABS) Halfords should sell this, once primed, leave for 10/15mins, then apply your basecoat paint, again allow 10/15mins to dry, before applying you lacquer
If you get it wrong, you could end up ruining your bumpers!

a decent 1000 grit paper to get a key , 2000 to smooth , then 4000 to flat , primer needs to b special plastic stuff so it can flex , as do the rest of the paints , it takes alot of time to get it right , if you want the full process let me know and ill wite it all down but , as beens said its best taking it to a baody shop , youll never get the same results from a rattle can
