Can anyone suggest a primer for plastic that will not react? (in a rattle can).

I've used Acrylic on a brand new side panel & the tailpiece with no issues - But I have come to do the front mudguard, and wherever the paint hits the bare plastic it's reacting & crazing bigtime!

Any ideas?

Cheers,

They sell primer for plastic..........Im sure they sell it Halfrauds!

Spray it on in light coats!

I'm sure I have seen it now... it's called Plasti Kote or something!

I'll try the local motor factor - I won't go near Halfrauds, not after they tried charging me £9.99 for a 472 bulb, I know the trade price of one of those is 60p!

Cheers,

Yep I've used PlastiKote before, good stuff

I'll invest in a can then... need to go to ATJ's anyway to get some more paint for the engine mountings. Need to do oil & filter in the Trumpf first tho!

They sell it at the Range & hobby craft, Don't use the plasti-kote laquer, it's not water proof, my front mudguard goes from Black in the dry to various shades of Blue, depending how damp it is, good rain sensor but dosn't look good (like the rest of the bike, I know)

Missus works in an Art shop, and they stock it, so not a problem!

Just hope the primer is acrylic compatible!

I think all the paint or primer are good on plastic, as it is paint with some flexible agent.
Are you sure there is no silicone repair on the mudguard, as this would react on the paint?

Well that's what I thought... I have sprayed a side panel & tailpiece with Acrylic and no problem.

The bare plastic on the mudguard seemed to be quite porous, as I took some of it down to bare plastic (where the paint was rough) and the difference in finish was noticeable. I'm just wondering if I need to get the fine wet n dry on it and smooth it right down by hand (did that with the tailpiece) so it's shiny. I used a power sander on the mudguard and only went down to medium (had no fine pads left)... so I'm wondering if that could be the issue.

Will have a look shortly. Too cold for spraying at the moment, and after the 13L & side panel aftermath, I'm not allowed to spray in the kitchen anymore

make sure it's clean, use some thinners but wipe it off again quick, or panel wipe. sand it with fine wet and dry at least 400 then use a high build or filler primer.
