plastic priming

[jamesandtheopenroad]

This might be a stupid question, but if i key plastic with wet&dry, can I then prime it for painting with etch primer? Or standard grey primer? Or do I need to buy a can of plastic primer?

Thanks

Not etch primer. It then depends on what type of plastic it is. Hard like ABS/Polystyrene or pliable like Polyurethane and what type of primer you call standard.

Bumper end caps and it's Frost's Grey Primer.

Plastic primer then, Halford's do a good one in a rattle can.

As Big herb says, I've used plastic primer for my big bumper set and side planks, covered really well. Rob

It's not a bad idea to find out what type of plastic the bits you want to paint are made from as not all plastics like being painted. Much of this is due to the release gel agent used in manufacture and some residue stays in the plastic surface and will reject paint, even if primed The most notorious one I can remember is for early Ford KA's when FoMOCO later began doing the cars with painted bumpers so some people tried to update their earlier cars and found the paint beginning to peel off in no time at all.

Hi,
On smooth plastic (cupd.door catches) I have used a plastic primer but I found that on wing mirrors/bumper end caps ie dimpled finish Plasticote, 2/3 light coats, lasts several years.

In work I use Tetrosyl plastic primer part number PLP010. Slop it in a spray gun and throw it on. Well dust it on twice, then you're done. Leave it 15 mins at 20 degrees C and then put on a high build primer. Job done.
