Our shop has been using 3M Ultrafina SE with a D/A polisher and grey Lake Country CCS pad as the last polishing step in our paint correction with great results for some time now. I was recently told by the distributor that 3M has discontinued this product and I'll no longer be able to get it. So now I'm needing another product that will produce similar results at a reasonable cost. I was paying $30 a quart for the 3M. Thanks for your suggestions.
