IPA mixing instructions?

hey, what dilution ratio do you mix IPA with dH2o?

 

sometimes it is 50/50, but I think dsms came up with different ratios for different types of clear.

 

I don't think it's that critical?

 

look for threads started by dsms. He did a good writeup of mixing different ratios.

EDIT: I'm bored:

Kind of is IMHO.

If your dealing with a soft clear coat and use too much alcohol your MF will get very grabby and may cause marring.

 

50% water
50% alcohol

 

What would cause the "Grabby" action there is nothing on the paint ie wax, selant or glaze.
And IPA won't remove clearcoat, maybe something in or on the MF?

 

Well having no wax or sealant actually adds to the problem, if the finish is 100% stripped of LSP, glaze, oils etc. it should be "squeaky clean" as in try to rub your finger on it and it squeaks and your finger stays in the same spot like pulling the E-brake in a car while driving down the road basically.

Wiping a clean finish with MF and QD works fine because QD has lubricants or silicone in them, they act as a buffer between the towel and paint and allow the towel to glide.

IPA has no lubricants so its easier for your towel to get grabby on the finish. Adding more distilled water as needed allows the towel to glide easier. You can wipe a whole car down with just distilled water and it works fine, not super slick but smooth enough so adding more of it to your IPA helps reduce the above problem.

The grabby'ness is not the whole issue, I explained in the little writeup I did also about hazing. I cannot explain why but some finishes get hazy when too much alcohol is used hence why I have different mixtures for different paints.

 

That makes sense, but what would cause a MF towel to marr the surface?

 

why not pick up Menzerna Top Inspection?

 

haha, ideally I would use this...yet I ran out today and needed something quickly....your shipping is damn quick Phil, but not THAT quick LOL

btw, +1 for Men TI --> Awesome product!

 

Phil, I think the cost difference between IPA and Top Inspection is the determining factor for most. Good product though. Worth having around for those finnicky paints.

 

Lol @ constant plugs



I use IPA straight up on every car
- What I do is mist the area and allow to dwell while I mist my towel. After a few seconds wipe(dont scrub then follow up with another light mist.

I do not like to dilute my alcohols when wiping because the alcohol is what acts as the solvent, dilution to me always result in more streaking - esp when using menz.

If you see marring after your IPA wipe then you need to change your towels. I have fortunately worked on very soft paint and the towels are the culprit not the "no touch" action of the IPA.

 

So you do not dilute your alch. at all?

 

Nope - 100% IPA when I used to use it myself.
Best way in all honesty, but I've since switched to slow flash panel wipe, as used by bodyshops.
IPA neat tends to flash too quickly, which means it drops what it picks up as the solvent evaporates.
Best thing I did - I see a truer state of correction since changing over.

 

hmmm, interesting. I may need to try this method.

 

What brand do you use and where do you get it, a local autobody supply house? Are you referring to body solvent?

 

Using straight IPA on softer clear coats will cause problems.

Dilute it 70/30 and just perform multiple wipe-downs to ensure true correction.

 

No idea of the brand, was given a fair bit by a bodyshop in the same commercial units complex another detailer operated from.
Similar to the brand name Prepsolv.

Used by them to remove wax/silicones/dirt/dust prior to repainting/repairing the panel(s).

As was explained to me, slow flash-off so the debris doesn't drop out of suspension while you're wiping a section of the paintwork.

Neat IPA just flashed off too quickly, and I don't see the point in diluting it!
Have also been informed it's not the kindest of products long term - in fact mineral spirits would be a better choice, in lieu of an approved panel wipe.

 

I would love to know the exact chemical make up of Top Inspection...
