As above will work better done by machine
Just to show what can be achieved here is a golf i did that was pretty far gone over the whole car
This was one of the very first cars i had done and was pretty pleased with the outcome, as was the owner.
Was done using the megs G220 Dual Action machine with sonus polishes and pads, First sfx-1 then 2 then 3 with matching pads each time.
Once outside you can see the colour better
