"rubbing alcohol" is an old name for it because the common man could not say "Isopropyl alcohol".

Now my question when everyone states 50/50 (water/IPA) what do they mean?

Before you jump "Post Quick Reply"

Does that mean 50/50 mix at 40% IPA (right bottle at top) or 50/50 at 70 % IPA (left bottle)?

The reason is I pick my IPA up at Costco (Canada) and they sell 99% IPA.

Because it makes a big difference on a 50/50 mix

At 40 % IPA = 20 %

At 70 % IPA = 35 %

At 99 % IPA = 49.5 %

I have used some of the 99 % in a 50/50 mix to remove some wax on a door jam and it worked maybe to good.

I think everyone should remember this. I always try to get 94% mix. This makes the 50/50 when mixing it with water close to the 50 of each product.

haha, what drug store did you go to? Both products shown consist of pretty low levels of alcohol.

Just go to a local CVS, they carry 91% IPA, $3 for 32oz if I remember correctly. You can use it straight or cut it 50/50 with water.

Bottom left of the green bottle = Phillippines. So he doesn't have access to a "local CVS"... lol...

I read that doing an IPA wipe down after polishing is a good step to remove any residue left by the polish,...

OK, I'm a bit confused.

Above I'm reading that the IPA wipe down followed the polish job, but later in the thread someone else confirmed that the IPA removes polish.

So.... why would you spend a bunch of time polishing and then remove it with the IPA? Is this just a typo error?

You want to remove the polish. Polish takes out the imperfections in your paint and after you polish you want the surface to be perfectly clean before you lay down your wax/sealant.

Ah, OK got it. I was thinking wax when I read polish. Sorry for the misunderstanding; I'm new round these parts

I guess it depends on what polish you're using.

WG does not recommend or suggest to remove the WG Paint Enhancer Polish prior to WG Sealant 3.0.

The 70% is good. Just mix 2:1 for the 50/50 mix. Here's the breakdown (yeah, I learned it here from another detailer that must have OCD like the rest of us, lol):
70 alcohol-30 H2O + 70 alcohol-30 H2O + 100 H2O = 140 Alcohol/160 H2O. Close to 50/50.

I'm not familiar with WG products, is that some sort of paint cleanser/chemical polisher?
