Sorry if this has been covered already. (I'm sure it was but I couldn't find it). 90% alcohol is hard to find. 70% is sold everywhere. Is using 70% mixed with 25% water or straight OK? How about denatured alcohol. Also is spraying and wiping the mixture supposed to remove wax and sealers. I tried it with the 70% and water still beaded on the hood. Is it bad to use Megs 105 without removing the wax first?

Wax should be removed in the claybarring stage of prep work.

I use straight 70%. My next bottle of it I will be buying the 91% and running it full strength though.

Water can still bead somtimes after a wipe down. Do two or so. You will see the true finish soon enough. Also, after you make a couple swipes with the same MF towel it'll be clogged up with the old IPA and will be easier to get the fillers out. It will probably streak at this point though.

Technically IPA is a form denatured alcohol so it won't hurt anything. All alcohol that is not meant for consumption is denatured so that it will make you sick if you try to drink it.

You can wash a car with Dawn to removed previous waxes and such before a detail.

I think I found 90% IPA at Target, I'll check next time I'm over there. If you don't mind spending $7.00 to $8.00 go to any Lowe's, True Value or Home Depot and get a quart of Mineral Spirits, it will remove just about anything off the surface and wipes down more clear. IPA tends to wipe-off and leave the paint looking all streaky and hazy causing you to wipe more to get a clear view of the paint.

Like zinc02gt posted, some paints will bead water without any wax, water beading is just a sign of surface tension and it doesn't take much to create surface tension on a smooth surface.


Meguiar's M105 or ANY abrasive compound or polish is going to obliterate any layer of wax or paint sealant off the paint after the first pad or two with any machine and any pad.

Just wipe the surface clean and then clean your pad and you'll be buffing clean and unhindered.


What are you working on?
What are you trying to accomplish?

I bought 91% at Walmart, less than $3.

Thanks for the tip about the mineral spirits Mike, I will have to try this!
 
I use Mineral Spirits and/or 91% IPA straight.

Some paints tend to wipe off better with one or the other, so I have both on hand.

You should be able to get the 91% IPA at Walgreens, CVS, etc.

Mike, just to note, not all polishes will remove a sealant right off the bat. I have run into a few cars were I had to actually take solvent to the car several times to remove the sealant. The wool pad/105 combo was just gumming up badly. As a rule I would agree most sealant/waxes would be removed with a polish.

That's where an experience detailer like yourself can stop, evaluate what's taking place and adjust their process accordingly.

One thing for sure, paint sealant technology is come a lot further in performance than it was just a few years ago.

Someone asked a few posts ago, but no one answered. Probably missed it, but do you dilute the mineral spirits or use it full-strength?

I am pretty certain that Mike uses the Mineral Spirits straight too...as I started this practice from a recommendation by him.

What about denatured alcohol? Is it ok to use.

Would that happen to be the big Z? A body shop nightmare.

One was the Z06 i posted on here in show and shine, plus a few others. When you go to polish and it isn't very smooth or the polish gums up you know you need to do a solvent wipe down to get rid of whatever is on the paint. This is why I ALWAYS do an IPA wipedown before polishing.
 
Thanks for all the answers and input. I have plenty of mineral spirits on hand. I will try that.

So I can use Mineral spirits prior to polishing to remove sealants/wax correct?

What about mean by solvent wipe down? Like megs body sovent? I know all the steps and everything but I always so interested in hearing these tricks people have, like using IPA. After wash and clay-->IPA wipedown then polish? Then after 105, IPA, then after 205, IPA?
 
What is the technique one should use for an IPA Wipedown? Spray it on a towel and then wipe, or spray the finish and wipe it down? It there anything bad that can happen to plastics, rubbers, or vinyl?
