MkII Plastic Heater Refurb'

[111Robin]

Does anyone have any experience with refurbishing a MkII plastic heater casing ?. I'm not sure if it can be blasted with a soft media or rubbed down with abrasives then painted. The surface has a grainy type finish that's impregnated with white particles, presumably from a previous spray job. Tried polishing with T-cut, made it shine a bit but appearance still not good. Advice appreciated :

Thanks Ian, I'll give it a try. Did you hand polish or use any form of rotary tool ?.

Polishing failed to improve the finish so decided to flatten, prime & paint (semi-gloss). I think the finish is pretty close to original :

That's looking good now. I hope it doesn't scratch showing grey primer.

Are you going to use letraset letters for the on off and screen ?

Haven't thought about the lettering yet Iain, just want to get it back on the car so I can get it running. I'll sort the details later. Getting there slowly....

Looks smart and like you said not far from the original finish

The finished article (minus switch). Still need to add the lettering on the front panel though (when I can be bothered!!)
