I was going to wait until my AutoSol ran out or I had something bigger to polish before buying some of the Britemax, but after spending a bit of time with the AutoSol on it... I still think it could be better!

(How frustrating... it wont let me display my images in the post. It worked last night in a different thread!

Its cleared off the rust which is the main thing, I will get some of the Britemax stuff and hopefully bring it up better still

Thanks
