I was unlucky enough to have a trailer without a clearcoat and MAJOR corrosion/rust/pits/you name it. I tried all the Nuvites and nothing would remove the oxidation. Another member suggested gravel in a bottle by 3M and sure enough it removed all oxidation... however leaves some nasty swirls. I have tried compounding with F9 followed by F7 and C but I am still seeing a large amount of swirls... nothing like you do after the 3m cut but probably more than if i had only used the nuvite series.
What do you guys suggest to try next or is it normal to see the swirls left by F7 or C before trying the cyclo?
thanks in advance!
