Hi mate,
I tried the SSR1 by hand and it made things worse, so just be careful. Hand polishing didn't seem to be enough to break down the abrasives suspended in the polish, essentially just rubbing grit around over the paint. I ended up trying GTechniq P1, which worked pretty well by hand although it takes a bit of elbow grease. Residue wipes off easily though.
After that, I took the plunge and bought a DAS6, yet to get the full benefits though - wasn't very brave first time!
Good luck, hope that little bit of info helps somehow!
