How long after laying SPI Universal should I wait to cut and buff? I shot the body on Sunday and the fenders on Tuesday. I was planning to start cutting on Friday. Is that an appropriate time frame?
I put four coats of Universal on, but I think I did it too lightly. I was probably moving a little too fast (afraid of runs) and didn't overlap my passes by 50%.. It was more like an overlap of 20% or even a little less. So perhaps my four coats is more like 2 coats. The car has pretty heavy orange peel throughout. I was using my Devilbiss 670 Plus gun with a 1.4 tip and 40 PSI at the gun.
Here is what I was planning on doing:
- Cut with 1500 using 3M No. 20 Wet-or-Dry sponge pad
- Sand with 2000 using 3M No. 20 Wet-or-Dry sponge pad
- Polish with Meguiars 100 and "medium-heavy" cutting pad on rotary polisher
- Polish with Meguairs 205 and "light-medium" polishing pad on rotary polisher
Does that sound about right? Should I start cutting with a heavier grit? I also have a Hutchins 4500 DA sander that I could use.
Thanks,
Sal
