Oh my..
PC and 4 hours of polishing on a small SUV is blitz fast... Im also a noob and it took me maybe good 8 hours to polish full car including breaks and taking photographs... I didnt make the mistake of rushing things because prepwork is what your finish will be so take your time and enjoy... Im stepping up to rotary soon to be a little efficient, but there is nothing wrong with
PC... GOOD LUCK
