[clashcityrocker]

i was looking for some advice

couple of years ago i replaced my wings and had them sprayed and
blended into the front doors
recently noticed they are discolouring

whats best for bringing the paint work back to its best

Discolouration is probably due to oxidation, UV rays contamination wtc.

I would of thought:

Wash area affected

Apply a rubbing compound thoroughly on the affected area to remove oxidation and contamination.

Use a polish to bring back a shine.

Then protect with a wax.
