Machine polishing will definitely improve the look of it. My kids wanted to draw on the door of the CRV with a stone a couple of years ago and a machine polish did a great job in hiding the worst of it.
Tbh I’m not sure on that product but I treated my gtc vxr which is out all seasons with xcp professional rust blocker, goes on like a thick wax and drips for about 2 days until it dries a bit, loads of **** then sticks to it and it looks a bit messy but I made the mistake of thinking it had worn off one day a year back.Next question....
I applied Bilt Hamber Dynax UC on suspension components - springs, shocks, arms etc. I did leave it to dry as per the instructions but ive noticed crap sticking to it in places. Rinsing with the hose and water doesnt seem to remove it easily so what can i use for rinsing up round arches etc. Would a mild mix of articulate be ok or would it remove the dynax?
