Final wipe down before ceramic coating

[Setec Astronomy]

A few random thoughts:

IPA isn't that potent a solvent
If I'm touching up a rock chip, I use it straight (well, whatever the supermarket concentration is, I guess 70%)
Most of the prep sprays are just IPA mixtures
The whole process seems a bit haphazard, take a not-great solvent, dilute it, add some lubricant(?) to prevent marring (which is what most of the prep sprays say they have), then wipe around a little with a MF...not sure how effective that really is
TRC video with Adam of Adam's, he said the whole prep spray thing is nonsense, the coatings have a solvent carrier, etc. Not sure I agree it's nonsense, but there's an opinion from someone who sells coatings
I kind of like the idea of a primer polish, where I don't have to worry about IPA wipe and whether I did a good enough job

Well I'm just a hobby mouse, I didn't even know much about prep wipes till this forum. I think at the very least when I use Eraser I am getting any dust or polish residue left, but mostly... it's that smell! The whole garage smells great and the microcloths I used act like an odor bomb sitting on the bench as I apply my protection. Just a pleasant working environment.

What would be your recommendations?
Have washed with Koch chemie AS shampoo.
What I can see the car looks good other than the halve of the roof with the stain look. It looks smudge like.

A finishing polish, move up as necessary including pad cut.

Sorry, thought I clicked on "like".

I see that Carpro Eraser & Gyeon Prep is very good for this, is this still true or is there better.
I was going to do IPA mix but have been put of by comments does work doesn't work, can make it worse spreads around instead of removing etc.
Watched a video with Yvan, 1/3 Acetone & 2/3 Windex.

Any other options/opinions would be appreciated.

The 1/3 acetone and 2/3 windex is a tried and proven solution. it's been around for decades, as we used to use it for paint prep back in the 80's. it's my go-to prep spray after polishing. Works great. Traditional IPA will not remove oils much at all whereas the acetone mix will absolutely remove them.

That's what I was musing on, mostly--body shop prep solvents are nothing like IPA, but all these coating prep products are diluted IPA. I was just looking at the SDS for the Optimum Paint Prep (because it was quick to find) and it's only max 10% IPA, and max 10% n-propanol (a related alcohol). So their prep is only 20% "IPA", at best. Methinks you would never use something like that to prep a panel for paint, but here we all are, happily using it for coating.

If the coating you're using has a panel wipe, I've read that's the way to go.

Well, I am using it. No one uses Gloss Coat anymore. Glass bottle beads are king in the detailing world. I don't live there though. Lol!

it doesn’t take a lot. I start with a few sprays on my towel and then a couple of sprays per panel. You should easily be able to do multiple cars with s small bottle of Gyeon Prep.

Is Gyeon Prep basically the same as Eraser?

I see a bit lately easing up on prep for coating.
