wouldnt it be better to sand them smooth then prime and paint them? Surely less to go wrong/crack/fall off/anger the gods/etc then?

He needs to use plastic primer then paint as normal. High build primer smoothes out the mottling on the bumpers.

rub them down a bit with a rough sandpaper then get a very fine sandpaper to smooth it so its not rough.

that type of plastic always risks flaking at somepoint anyway, a lot of decent bodyshops will refuse to paint that type of plastic at it traps moisture and they cant guarantee the work

difference in the plastic that vauxhall have painted it fresh from the mould and not suffered the weather and cleaning products which will mean it has absorbed moisture and silicon
very hard to get it all out, and even if you prep it loads still runs the risk

Yes of course it does steve. It's got nothing to do witht the fact that Polypropylene is a naturally oily polymer.
Bodywash cleans off the silicone, and the plastic doesn't absorb water.
How many bumpers have you painted, you seem to sound like you do it every day.

So they think that Vauxhall bumpers get made and then painted straight away with no exposure to air?

So what does rain do to a polypropylene bumper then? It's not like that material absorbs water is it, or are builders also wrong for using it for waterproofing roofs?

traps moisture in the texture not, the plastic?
im just saying what they told me, because they refused to paint this lads plastic textured bumper as they couldnt guarantee it wouldnt flake. Adnt that was the reason they gave
