I have a modifyied, rollbar, but would like a good gloss finish, so can i get it plastic coated ? if so who and how ??

Im in west sussex,

Do your own with one of the plastic coating kits available cheaply and a hot air gun?

No!!

Plastic coating is not all its cracked up to be, get a local small bodyshop to 2 pack it. More durable, repairable, cheaper, more practical.............

I was thinking along that line anyway, as my wishbones, could do with a revamp
