Here's a comparative photo of the two pads. I also recall now that we had a thread a few years ago about Scotch Brite Pads that some members were concerned that Scotch Brite Pads had metal fragments in them. I did a scratch test thusly: With a knife I scratched a SB pad over a piece of white computer paper which produced some small flecks on the paper. I then held a magnet over the specs and some of them jumped up to the magnet, thus proving that the worriers were right. Some folks said they didn't care and would use them anyway, whereas others who, for example had engines with Magnetraction, decided they would not. For this reason, maybe those you described as "blue, scratch resistant" may be the ticket if they are the right size (thickness).
