While waiting on another weather window I have been sanding out my last spray job and have a couple questions before moving on to buff and polish
1 I used the assilex/buflex papers for most of the car. However before landing there I tried a few different papers/methods starting on the roof. Sunmight, wet and dry, and another brand I forget who, before settling on the eagle stuff dry. I went up to 2500 with sunmight then 3000 buflex and finished with trizact 8000 wet. I did a quick wool pad with 3d 500 to see how it looked and I'm happy with the shine but I noticed a few scratches. I was a stickler for sanding each grit in a different direction. So based on the scratch direction it is either the 2500 or the 1500 where I left scratches. Now I am wondering if this is because the sunmight cut deeper and if I my issue is just here or on other parts of the car that I did completely in eagle. I spent a lot of time checking each grit with a light for removal of prior grit scratch but these made it past me. when you get this, how far back do you step? Go back to 2000, 2500, 3000, spend more time with wool?
2 I worked each git step when sanding . knock off peel high spots and dust nibs with 600. Flatten orange peel with 800 until about 70-80% gone. Then 1000,1200,1500,2000,2500,3000 then trizact 8000 wet. doing this much sanding, is it still advisable to go wool pad then black foam with the 3d 500/520 system, or do I skip wool pad. I'm just wondering if the wool step is a pro or a con since the possibility to hit and edge and burn through (yes I am taping) is higher here.
3 When buffing particularly with the wool pad will areas like these trim holes in flat panels be an issue for burn through and if so how do you protect them?
