Sand, plastic primer, sand, then 2 layers of paint should do it.

Back in my council days I sprayed my eyebrows in the above order and considering the flexing I gave them before putting them on, the same method should be fine for your plastic bumpers.

One can of primer/paint (about 12 quid for the pair I think?) in Halfords should be enough to do both bumpers. Remember that the trims (the bits that go round the indicators) just click on and off so don't waste your time


Cheers Zayyan! Appreciated Mate! :D

Paul,fair play to you for trying mate,many people wouldnt even have attempted it!

Personally i love spraying,never actually sprayed with a compressor only aerosol on smallish parts and there is a real nack to it,room temp,dust etc.

I always find that spraying the lacquer is the most difficult,getting it even and not to thick.

When spraying i usually go for about 2 coats primer with a 1200 grit rub down in between and after-then about 3 coats of colour, rub down with 1200 in between but NOT after the final coat-then about 2-3 coats of lacquer on top.

I also use a heat gun to warm over the lacquered area for a while but not too close,then allow to dry overnight!

Next day,lightly go over with 1200 or higher keeping very wet/soapy then dry,quick polish in and done!
Finish is never going to be as good as spray gun job but good results can still be had from a rattle can winkeye

Oh and the bigger the panel the harder to get a good finish/blend.

All this info is based on my own experience!
Heres a pic of some SE skirts i painted this week for Benjys car this week-

Thanks Tony.

Your right, most people i spoke to recomended i didnt do it myself, and maybe they were right, but its not too bad. I think i messed up on the lacquer, but with a polish im hoping it will look good.

Its all on the car now, and im happy enough for now :D

Those SE skirts look great, realy nice finish on them. Well done :thumb:. Cheers for the advice, but i think i will steer clear of spraying for now!!

Off to clear up dads garage :roll:

I tried it myself on a front valence as I figured I had nothing to lose.
2 coats of Primer, 4 coats of paint and 5 laquer.
I then started to polish, lots by hand to start with and was dissapointed witht he result. After a week, I used an electric buffer with some polish and after a few goes and a couple of washes with Maguires (sp?) it came out fine.

Not the best picture, I'll get another one later but:

Just to chuck in my 2p, Would it not benefit from a wet sand? as was mentioned above really fine paper and lots of soapy water.

Other than that it looks really good. Well done

you only need to use plastic primer if you have sanded below the original primer if the surface is good i was recommended to use a scotch pad scrubber to give the surface a key then to flatten the paint with wet paper until the final coat before laquer as said earlier in the post
