Help with sanding marks after buffing

I can't tell what's going on there. But just fyi, the last part of the Perfect Paint Job tutorial, in the "Layering multiple coats of clear over multiple days" section calls for three coats plus three coats, not three plus two. If you only did two on your last round, you are in serious danger of rubbing through.

Rubbing through to the base?
I shot the 2 gallons that I had, was only able to do 5 coats which I thought was pretty good.
 
Rubbing through coats 4,5 my guess & now seeing sanded 3rd coat.
If disaster struck, and you'll have to give it 3 more coats, block any waves you left behind and you'll have a beautiful job.
 
So to fix ill need to give it a few more coats of clear.
What grit should I hit it with to get good adhesion?

I dont think I am that deep into the clear, when these spots started coming up I worked on them pretty hard with 2000-3000 and they only grew outwards. That is why I am thinking I burned through the 2 coats I applied the second day.
 
rough grits is what got you into trouble in the first place. either you are bucket sanding with mud ( not rinsing enough ) or you failed to get the heavy scratches out with 1500. 1000 scratches are deep.
1 min of 1000 will take 3 min of 1500 . as you go up the scale it takes longer .

I think bucket sanding is what got me here, I didnt spend too much time with 1000, only in places where I had issues.
I switched to a spray bottle and have gotten meticulous about cleaning the paper and flooding the area.
 
i have a 1/4 in hose with a spray nozzle in my booth where i sand. i keep a clear fuel filter on it and it is insane what comes out of my well. was worse in town with all the rust .
keeping it clean is all important . something as small as a cottonwood seed can put 80 grit scratches in it. i use my hose and rinse constantly. buckets are a disaster waiting to happen and a rag is worse .

#32 and a white pad will cut pretty quick. if your not going to do the sanding steps get the marine boat compound . it cute really fast but money bet is your more likely to burn up paint buffing faster than polishing after sanding .

I have read this twice about the white pad ,,will this cut faster next to the orange pad chemical guys hex logic?
 
orange and yellow are cutting pads . white is a heavy polishing pad. read the descriptions of the different pads. there are multiple cutting pads and multiple polishing pads .
 
So what white pad are you refering to with the 32 ,,sorry maybe im confuse and need to read more
