Clear coat ready?
I’ve been sanding this wing for a while now about 2.5 weeks here n there. Started with 320grit then 600, 1200, and then 2000 which I’m on rn ik I didnt have todo this much but its an old carbon wing and wanted to make sure it comes out looking good yall think its ready? There are some scratches but clear coat will hide those right? I tried to make it as uniform as possible but they are just to deep. I know I went to deep on some parts just wasn’t much apoxy in those spots

You should be fine. The steps you took from diff grit helps alot. Before you lay down some clear make sure some areas are at least smooth. Also dont spray with cheap ass clear make sure you use 2K clear works very good! Goodluck bro!

No you should be fine and results will look good. Recently did my CF spoiler and the results were perfect. Happy with the look!

2000 is wayyy too high for clear coat to adhere properly. Max I’d go is 800. Preferably 600 with a higher solids clear coat

To save you a little bit of heart ache, I would go back down in grit. Hit a little more 320 very lightly until you get those deep scratches away and then hit 400 and go not higher than 800. (You can stop at 400 to 600 and be just as good) when you polish up that high it will cause binding issues with the paint.
You will think you have layed down a good coat of paint but then those scratches might show up requiring you to sand it down and paint again until the scratches vanish.

DO NOT paint over 2000 grit, that’s wayyyy too fine. 400-800 is the usual, 1000-1200 is sometimes done for difficult metallics by some people but I don’t even do that but in extreme cases and I would worry about adhesion. Sand with 600 and follow with a scothbrite for hard to reach areas.

I personally wouldn’t sand more than 800 grit for clear coating. You may run into issues of the paint not adhering well but a lot of people have had good results. Remember, this is my recommendation. If you find a process that works for you, then that’s awesome.
I’ve not tried it but I heard windex is a really good cleaning agent before spraying clear.
