I'm about to paint the black parts of the bumpers on my pre-facelift 145.gif as they're a little bit scuffed and faded but don't remember what colour the plastic of the bumpers was any more. blush.gif

I think it was dark grey but most people's bumpers look black in the photos. unsure.gif

Does anyone know?

They should be a dark grey - if left alone they can fade much lighter... I use a 'back to black' bumper wax, which adds a nice lustre and makes 'em look new.

Thanks Hazey, Dark grey it is then.

Yours shows it quite clearly. I got a bit confused by this brochure shot but I guess it was a prototype.

I just scrubbed all the Back to Black off my bumpers ready for the paint- they look absolutely terrible now.

My signature pic shows a bumper in need of waxing... and having a black car makes it look lighter too.

The photo attached was shot just after it was done, looks much darker.

I'm sure 145 in the publicity photo will have had the same bumper as ours, just with lots of dark wax and a nice moody location.

I agree. Don't paint them it will just crack and look sh1t. Try some black in flash or the like and see how they look then. You might need to give them a couple of coats, but some say they hide the scuffing.

I have a 130 Rosso red car. Getting a colour match might be a struggle.
I am also trying to keep it as original as I can and quite like the original look.

Is the cracking problem common to all bumper paints? The stuff I have says it can be sprayed directly onto the plastic.

Has anyone tried Vinylkote yet on bumpers? I used it on a vinyl sunroof and it worked extremely well.

I have been over it with all manner of scouring powders and detergents to get every last trace of wax or silicone off.

My car's bumpers have at some point been colour coded to the car. the front bumper is fine (no signs of cracking etc) but everytime i wash the back bumper under the numberplate more flakes come off blink.gif i assume that is because all the water settles there and helps dissolve the paint?

i'd reccomend colour coding though, it just makes it look like a facelift and for the price it lasts quite well - i suppose it depends on the colour of car and how well black bumpers go in the first place.

Try Krylon Fusion which is specifically designed to be sprayed onto plastic without cracking or flaking. It isn't available off the shelf in the UK (I think due to the type of hazardous solvent used in the paint) but you can get it imported from the US through Caswell Europe. The page with the Krylon Fusion paint is HERE. They do black in both gloss and satin. Quite expensive at 10 a can with import charges (not sure if this also includes delivery) but if it does the job properly then it will be worth the money smile.gif

I might try that as the paint I bought is too light and has already scratched off the lid of the can which isn't a good sign.

Have you used this or seen the result?

I like the idea of hazardous solvents bonding it to the plastic properly.

Not personally used it myself, just heard other people recommend it elsewhere. There's some more information HERE and a review HERE.

i got some stuff from my neighbour, the back to black stuff that he uses at the garage to sell second hand cars, it works very well although does benefit from a weekly dose to keep eveything in pretty condition.

It's crazy sometimes, he brings his homework home with him, on a sunny evening he waxes, sprays wipers, polishes, hoovers etc and can turn a car around from looking a bit ropey to A1 condition, guess thats how they make their money, bit of spit and polish.

I'm a big fan of Back to Black but the colour of my bumper is patchy and almost white where I have tried to even up some scratches it has.

It will need some colour. I just tried a light coat of the Hycote dark grey bumper paint I bought on a plastic wheelie bin and it seems to have bonded really well. Just a shame it's the wrong colour.

Here's the sh*gged bumper and I've got a can of black bumper paint (dark grey is too light and they're almost black when back to blacked properly).
I'll give it a quick run over with acetone, then 2 light coats and see what happens. unsure.gif

Fantastic job...looks like brand new biggrin.gif

Out of interest, what did you use in the end? Is it some stuff which adheres properly to plastic and is guaranteed not start to cracking or peeling off?

2 tins of Halfrauds black plastic bumper paint (about 10 for 2). No guarantees. sad.gif
It sprays differently to paint where you let it flow. With this stuff you dust over in about 3 or 4 very light coats. Too thick and it goes white.
It's meant to be black but this photo shows that it appears dark grey when sprayed onto the textured bumper even though the smooth lid is black.

I am hoping that the cracking would be down to coats that are too thick and the peeling might be a result of not getting all the old Back to Black off. unsure.gif

Hi laaf, the bumpers do look awesome, just wondering how theyve lasted ? any sign of cracking/peeling/fading etc. ?

cheers, tom.
