I must admit, this is the first time I have had this kind of problem but, recognize that is largely my fault. Not only did I use the 1500 but, I over used it. I made 6 to 8 section passes assuming the 3000 would remove them. I overused the 3000 and realize now it is good for 1 panel or approximately a 4 x 4 section at best. The slurry does indeed turn to foam and, is the only indication the 3000 is worn slam out. Additionally, it is likely to be putting little orbit worms in your finish.So all the work I was doing was for not result.
I also wipe down with micro fiber after each sanding operation. That reveals little but, if you wipe down with wax and grease remover on micro fiber, it will show your scratches.
It took me all day to produce this in the first cut ( 2 passes ) of 3M Perfect it compound

The last car I painted with PPG sanded and buffed with 3M. But, I did not lean on the 1500 so hard, as I recall. The finish was like glass and nib free prior to buffing...
Just so I don't look like a complete idiot...:disturbed:

Has anyone tried the Norton equivilant to trizact? It is much cheaper, I am told. They do not make a 5000, though. 3M trizact 3000 and 5000 cost me about 5.00/pad. Guess that is why I was leaning on the 3000 so hard. By that I mean, stretching the use...
