Ceramic Coating issue, help requested

[Rocker1911]

I had a B7 A4 that I prepped and coated. I had some issues with the way it turned out, I am just looking for someone to tell me what I did wrong, and how I can avoid it on my next car?

I made a concoction of dawn dish soap, chemical guys clean slate, and chemical guys bug and tar remover in a foam cannon, I let it sit for 10 minutes. I then hand washed the car with chemical guys clean slate and bug and tar remover in a bucket with water. Rinsed, then sprayed with Iron-X, I let that sit then rinsed off. I then used a auto scrub clay sponge and chemical guys clay lube. Rinsed the car again, then dried it.

I then used a micro fiber cutting pad and chemical guys v32 compound to cut out the nasty defects from a bunch of wet insulation falling on it (long story), then went over it with a hex logic orange pad and sonax perfect finish. I did not end up polishing the whole car, I just wanted to get the nasty stuff. After that I wiped down the car with car pro eraser.

I then put a layer of car pro cquarts UK 3.0 on. I did a part of a panel at a time buffing off after. I let it dry over night and put a coat of car pro Gliss on top. I then let it sit for 24 hours and then applied a layer of car pro reload.

Unfortunately the lighting was insufficient and I missed buffing off in some spots and the "rainbow streaks" appeared. Over time I noticed a few more. Then after about 2 weeks I was able to wash the car with car pro reload. When I rinsed it off and dried the car I noticed even more of the "rainbow streaks"

I was wondering what is causing them, and why I am seeing som many more after the wash than right after I did the coating. I will admit to missing a few spots, but this is excessive.

Did I put it on to thick? Did I not change out towels enough when buffing off? should I be doing even smaller sections, and buffing off almost immediately?

here is a quick pic of what I am talking about:

better lighting is all that's needed to make sure you get it leveled. Work in 2x2 areas too. the high spot you show there is not a big deal. get some car pro essense+, lightly rub it / level it down and buff off. or simply grab regular essence and do the same. Once done with essence however, you can grab some coating, re-coat just that general area and you'll be good to go. The coating will bond just fine.

Looks like you just simply missed wiping off that spot. Overall on pure black coatings can be a PIA at wipe-off and nothing beats viewing them under cloudy conditions once done. You have about 1hr from it's wipe off to get any lightly matted areas smooth.
