So I recently spent an entire day Saturday using a DA polisher for the first time in my life. Like you, i had a free bottle of Resto Max that i decided to try on a tuxedo black Ford Fiesta. I used 3" hydro-tech orange pad which were on clearance. I also had a bottle of Meguiar's Ultimate Polish...
not sure if this is still an issue, but its a virus/malware on the vBulletin server. other forums using vBulletin have this same issue too.
but thanks for the good info as always.
