Did a paint job, and for the clear used universal clear.
Had some orange peel so I wetsanded it all out. The clear sat for 24 hours air drying before I began this process. I started with 1000 grit and did a lot with that and knocked all the orange peel out of it. I wiped it all down. Got it wet again then hit it briefly with 2000 grit.
Next I cleaned it down and went to buffing with my Makita Rotary. For buffing I used the 3m Perfect-It products (compounds with their 8" foam pads). I started with the White compounding pad and Rubbing Compound. Hit panel twice with that. Then I wiped it all down and swapped pads to the black compounding pad and the machine polish.
I have excellent gloss and shine with zero orange peel. However when I angle the panel in the light I still see tons and tons of circular scratch lines from my sanding. I don't believe it is buffing swirl marks.
So what is going on here? Is the rubbing compound and white pad just not aggressive enough to take out those 1000 grit marks or something ? Do I need their extra cut rubbing compound to go more aggressive? Is 1000 grit just to aggressive? Should I spend more time sanding with finer grade or maybe do 1000,1500 then 2000?
update- Spent some time googling this and looks like the white pad and rubbing compound is good to 1200 grit and finer. Also the extra cut rubbing compound I mentioned still says 1200 grit or finer. They sell a super duty that is good to 1000 grit marks. I figured me sanding with 2000 over the 1000 would take out the 1000 marks, I guess not.
Idk curious to hear from you guys and get some tips on this before I do the big part of my job. Today was just a small panel ( storage door for my boat dash) but I need to get some best practices in a hurry and get this job done. The dash itself is a lot bigger job and there is some orange peel. Is sanding with 1000 a mistake? Should I start finer... I just worry it will take ages knocking down the orange peel with a finer grit. But if that is what it takes to avoid scratch lines that don't come out ok. Just want to know best way to proceed.
