   Want to paint my OE black plastic bits like mirror bases and exhaust heat trims but want to keep the pitted/matt finish?
   
   Basically just to get around applying bumper care... just looking for something maintenance free that will always look good and deep black.
   
   Think sanded flat and gloss black will be too much... suggestions on technique/paints please
   
   Thanks

   The idea of sanding stuff prior to painting it is to give the paint something to bond too on a normally flat surface, so if you just give those things a few lioght coats of primer paint and laquer youll keep the texture without sanding i would imagine

   ben your kind of right but its on a microscopic scale, not bumps you can see and feel. paint wont stick any better to that than a flat surface.
   
   you will still need to 'key' the surface to get the paint to bond.
   
   you key the surface with about 600 grit wet and dry which still looks flat and will feel smooth to the touch but it give the paint something to bond to.
   
   
   i dont know of any way of painting it and keeping the texture

   Couldn't you use the plasic primers - the resin type stuff that you brush on and it keys to the surface as it dries? Obvs you would need to degrease the plastic well before starting to remove all the old polish etc. This would avoid the need to sand.
   
   Then just apply paint in very thin coats so that it sinks in around the texture as it dries.
   
   The strips on the bumpers of the car i'm breaking have been painted (shitly) and you can still see the texture

   didnt sand the bump strips down on my astra, just primed painted then laquerd. worked out fine. never peeled or flaked off or anything, as long as the surface is clean it will be fine, just buy some aerosol surface cleaner like the one halfords sell. im doing mine when i get it back if it doesnt get wrote off, nothing worse than grey faded plastics.

    you wont need to key it, keying is just rougining the surface to give the primer somthing to hold on to. the plastics are already rough enough.

    it may be 'ok' without keying the surface and doing the proper prep work but you would never find a top bodyshop doing it that way. they would do it properly.

    Go to local automotive paint suppliers, ask for either ultra fine or very fine scotch brite, this will key the surface without taking the texture away then you can also got some plastic matt black(can get a range of shades) and use that then you wont need any grey primer etc.

    yep you want an ultra fine scotch ( grey normally) just because it is textured does not mean the paint will stick to it, like stated above you still need to form a key on the plastics.. You can do it with an arosol or with a gun using matting agent to get that satin effect..

    Ok, Danny did you flat back the texture on yours? Hard to tell....
    
    So fine scotch prep, plastic prime then satin black paint (or replace the scotch with flatting back with wet and dry)
