Hey gang. I am about to have a big push on the estelle and now need to paint a load of plastic parts. Some of which are wheel arches that are likely to flex a little. What is the best paint for plastic out there that is commonly available? Lewis P.s. in satin black flavour!  |

normal 2k gear is flexy enough for that anyway
its the spongey stuff like mk3 xr3i rear spoilers that are a problem

Ok thanks!
What sort of can based stuff would be suitable? Plasticote (sp?!) stuff?

The acrylic stuff in 'off the shelf' cans from halfords are pretty good on those sorts of plastics  |

If you are doing it from rattlecans, make sure you use a good plastic primer, and spend a lot of time cleaning and de-siliconing the plastic. I'd recommend a few good washes with soapy water and a scourer/scotchbrite, then flat out the texture with 320 grit wet.
Then another wash, proper degrease with panel wipe and only then get going with the plastic primer.
Even if someone, somewhere a decade ago decided to back to black them you are going to get grief.
I had this painting the dash plastics on my Lupo, and with the actual (metal!) dash on my mates t25. We had flatted it almost back to metal, put many coats of filler and high build primer on after serious cleaning, and still got massive fisheyes when we put the topcoat on.

halfords sell a high build plastic primer and its one of the few paints i would buy from them, as its actually really good, once you get a good covering of it, you can just paint like you would a normal panel. ive found spray engine degreaser works really well for getting rid of any nasty silicone based products that might have been applied to the plastic. its fairly cheap too

As the guys have said, you need some plasticiser on there whatever.
If you're in Wycombe then I'd suggest Morellis for the paint etc. Saves hiking all the way down Loudwater way to Halfords and might be cheaper too.

I've painted plastic in cheap primer and rattlecans before. Just primer it, let it dry and then put loads of coats of paint on top, and then let it dry for a couple of weeks indoors before putting on. I did it with a rear bumper, and even the slightest warp while it wasn't dry properly left crazing all over it, I had to start all over again and sand the lot off.  |

Ok. Well plan is wash, sand, wash, plastic primer, then I think some satin back plasticoat stuff.
I have had some problems recently with high build primer from halfords. It resulted in mega crazing on my spoiler (fibreglass) which took ages to get out and right, so I don't want to screw up fiddly things like door handels etc.
I will test the above combo on some scrap parts first to make sure it will work ok.
I could shoot 2k as I have a spray gun and air, but I don't need to paint many parts, so buying a load of 2k and primer and plasticizer seams a little overkill/spendy.
Thanks
Lewis

^ halfords standard primers are a bit naff, but they do one specifically for plastics and it really is pretty good stuff. ive used it a few times when colour coding bits on my polo and never had any issues with it

Well to close out the thread. I purchased Halfords plastic primer, and halfords satin black paint. and............. It worked! I cleaned and washed the parts, keyed and then washed again. Some of the primer in light coats, then on with some solid coats of black and it came out pritty well. Some pics    So that combo seamed to work well on my plastics. Thanks for all the tips. I was just concerned given the bad reaction I had on a recent paint fiasco! Lewis |
