Sorry. Missed this.

I use a dynabrade black. But, it is like 20yrs old , They may not even make them anymore.

Probably most DA's come stock, with a psa pad on them. Because, it's the basic "old school" stock/cheap option. Where you can use PSA's or glue on disks. You should be able to just buy a 3M H&L pad and change it out, if you want. Assuming you don't have some odd ball import DA.

If you're using off brand psa disks that may be part of your issue. Or, possibly the adhesive is just degrading over time. Since you use them infrequently.
