240 Isopropyl Alcohol to Degrease Before Painting?

I use isopropyl alcohol at 91% proof in the garage but not yet for paint prep. Will it do a good job at degreasing, removing silcones, etc?

Careful it will inhibit the curing of urethane products.

I've used it, no real benefit over cheapo Duplicolor Grease and Wax remover unless you already have cases of it. I would let it dry for a while before spraying.

Straight 91% will evap pretty quick, so I dillute it 10% with distilled water so it doesnt evap befire I can wipe it down. So far, no fish eyes, no cobwebs when using rubbing alcohol.

Now, some wax and grease removers, I have had problems with cobwebs, like 3x on the same panel. So After reprepping, I used straight 99% rubbing alcohol, and everything went smooth.

Acetone is a dry solvent and won't mess with urethane.

and dries without residue in about 10 seconds. I'd use that as a final wipe down. For degrease and stuff, I'd use a strong wax and grease remover. Something that doesn't evaporate so quick to get into deep deposits. I've used kleen strip prep all with good results.

Plus it's instantly in your bloodstream if you don't wear gloves, so win win.

Just put on you tyvek and face mask and wipe it with MEK.. or dont and experience first hand what Parkinsons feels like at 40 years old.
