   I was thinking of colour coding my bump strips but most cars i've seen it on (namely chavs), it always flakes off over time? Though i have also seen it done well, is this just down to using proper plastic primer or something?
   
   Any tips much appreciated

   Aerosol will always flake and go dull because there always cellulose or acrylic. The only way to get them looking good forever is to get them painted professionally with 2k paint and baked in a booth.

   i sprayed my arches on my old corsa using rattle cans lasted a year before i went down the fully respray route.
   like said pre,prep,prep i used thinner to remove all greasy bumper shine residue /etc prep thoroughly then plastic primer 3 coats ( preping in between) then paint (again 3coats) then lacquer. and polished.
   Also sprayed numerous alloys and never flaked off.

   Prep work is going to be critical, best bet if your wanting to do it yourself would probably be plastic primer, standard aerosols then try get some 2k aerosol laquer to seal it up properly.

   Single pack aerosols react with 2k paint.
   
   If your wanting a good hard finish that will last the lifetime of the car with bumps an scrapes then get the pro's to do it.
   
   Aerosol is fine but is soft and cant take punishment like 2k paint can.

   As far as i gather, when the plastic bits are made there is a release agent used in the plastic so it doesnt stick to the mold, and this stops paint front fully adhering, IIRC using a heat gun carefully over the plastic then cleaning it with an alcohol or thinners type solution will get rid of this release agent and the paint will adhere to the plastic properly. Hope this helps
