Hey guys, so here`s my question. Last July I applied can coat to my WRX. I clayed and decontaminated as usual and went over the whole car with megs 205 which by the way was the only thing I could get to finish clear on the insanely soft black subaru paint. Then I applied the coating. The car is not daily driven and spends most of it`s time in the garage. I`m extremely careful with it and there is basically no marring on it, thus I dont believe it really needs any polishing at all other than a few small areas. This year I want to apply another coat of can coat but do I need to polish it before applying again? Or can I just give a good wipe down with prep and put on another coat? Is polishing absolutely necessary before coating? Any advice would be appreciated.
