IPA Wipedown, Yes or No

I agree. If it is the proper thing to use before painting, then it should be more than sufficient prior to a coating.

I will wipe the car down with M37 N-914 after polishing before a LSP. Not at the paint prep ratio before applying sealants/waxes, about 1 oz per 32oz bottle. For peace of mind that all the smudges from polishing were removed and final dust removal.

You can skip IPA with a lot of products, I prefer to use it to clean the paint up after polishing because it's effective at a visual level when using a light source and glossmeter to confirm. Flashes clean, never leaves its own detectable presence visually on the surface for me. Some of the recommended solvent based prep products are much heavier and will flash slower, which is better for actual wax/grease removal which is something IPA won't do, but most likely overkill for removing polishing residue and I'm more included to follow these products up with an IPA wipe after use, even with one scented and colored like Eraser.

As a chemist, if I were to feel the need to do a final clean before waxing/sealing, I would use ethanol on a cloth just to remove particulates. Ethanol would also remove trace amounts of water but is less likely to damage the paint.

Hey Bill.

Could you elaborate on this?

Interesting! Gtechnic Panel Wipe is based on Ethanol. And from many who uses it is more satisfied with it than the Gyeon PREP or Carpro Eraser. Which are ipa based products. They are not the only ingredients in them but have some smaller amounts of other chemicals in them all too.

I'm with Loach and use them more for the visual inspection after polishing. Even if the polish or compound not has fillers in them. The polishing oils can mask the true finish a little. Not that it's very common it does so but sometimes it do.

So would it be straight ethanol or diluted to some percentage like IPA at 20-30%.
