Hello Jim
I have not heard of any in Portsmouth but certianly would not use the one in southsea behind Debenhams, the guys there look like there more suited to ringing cars than polishing....
I can however recommend as can other fellow Poorboys fans Nattys paste, fantastic product and so easy to use, leaves a true deep wet look shine on the car. With an added bonus of smelling like hubba bubba.
Any news on the retro classic you were looking at
