Hello jaykay
Don't know if you mean this thread about stainless grind and polish with one disc, I posted it a little while ago and a few of the members took up the web-site offer of a free disc to try. give them a try, you have nothing to lose.

( metalworking ) ......... and they do a scotch brite coarse disc that is velcro backed and removes metal and polishes. three grades. ask your 3m rep...... super for ali....... they dont clog... used them on a lorry tipper body.. invisible joint after using them......... all the best Frankie.......
