DP Coating Prep Polish vs IPA

[psaiko]

Hello from Germany!

I have a lot of coatings in use like cquartz, gyeon, modesta, echelon and many more. But there is one very important question.

What is the best preparation for a glass coating if your paint doesn't like IPA wipe downs. I often get some very very light scratches after IPA wipe down.

Some of my friend picked up a bottle of DP Coating Prep Polish last year.

I used this stuff on several cars with Echelon. Until now - without problems. But this is no really "long term testing".


Today I have played around with DP Coating Prep Polish and IPA (Spiess Hecker 7010).

I took some pictures.

Beginning:

Bonnet was wet sanded some month ago with Rupes Duetto and 2000 grit. Please ignore tape description and the "polished circles" ;)

I spread some Menzerna 203S (2500) on this test spot by hand with an orange spot pad.

Then take of the polish "residue".

Left side was given an IPA Wipe Down with Spiess Hecker 7010
You can see the difference.

Right side got two DP Coating Prep Polish hits. As you can see DP Coating Prep Polish has darkened the right side a bit.


1st hit.

2nd hit.

Let's have a look what IPA will do to the right side.

Ok. Both sides look similar now.

Ok - now my questions.

Why does the side treated with DP Coating Prep Polish have this darkening effect?

How can I see that all polish residue has been removed?

Is there really nothing left on the paint which can affect the glass coating?



Thanks for reading and hopefully answering my questions. Please apologize my english :)

My view on this one may not be very popular. As far as I am concerned, creamy emulsion polishes/cleansers will contain a number of non-volatile (i.e. will not evaporate away) ingredients as well as likely containing low volatility oils (they can be more highly volatile, but this is rare). I believe that it is likely the latter which is causing what you have observed. Basically, there is an oily film which remains and that is effectively giving you a 'wet' appearance. If you left it for a few hours, there is a good chance that this would disappear. As it is, your wiping with 7010 (I should be very clear that this is NOT IPA), will have lifted these oils.

As a side note, IPA wiping (that means isopropanol - a polar solvent, and alcohol) is at risk of marring paint because it really does not have anything much in the way of lubrication. Panel wipe, like Spies Hecker 7010, is fundamentally different. It is more like your gasoline or engine oil than it is a bottle of vodka - it will tend to have a higher degree of lubrication so should have a much better chance to avoid the damage. Further than this, unlike IPA (which is chemically defined), panel wipe can be many different things and the most significant for detailers will be the rate of evaporation.

Thanks for your reply! Of course I know that S&H 7010 is not only containing IPA - but it's shorter to write and maybe more people know what I mean ;)

The prep polish was designed specifically to precede coatings therefore NOTHING is left behind. You need to wipe it off completely of course. The above posted can postulate all he wants about what's in it. I have talked to the man who invented it. I have personally been using this product for several years on several different types of coatings. NONE of my coatings have failed. Take that to the bank. The only thing I'll so sometimes is to wipe the panel with an ONR dampened mf to make sure the panel is completely bare of the product after wiping. It's an unnecessary and OCD step, but it takes virtually no time and that way there is no dust or anything on the surface prior to coating.
Hope that helps.

Maybe it darkened the 2000 wetsanded paint that much because MF towel isn't able to get 'resedue' out of the very very fine sand-marks?

I really could not image that CPP will leave anything behind.


I did same test with Modesta P01A (Primer). Same effect here..

There are any number of similar products, we manufacture some. Just because you spoke to the guy who comes up with something does not mean you have the full truth.

I should also point out that onr will also leave a residue.

I prefer CarPro Eraser to IPA - not as "grabby", and plus it smells awesome. :D

PiPUK - I found this info during a search and I must say - very good info. Thanks!

Are there any corrective abilities for DP coating paint prep?

Its product description says:
-It is non-abrasive. Instead:
-It contains an "advanced blend of chemical cleaners".

But you know that a product's abrasiveness can often depend upon the tools/pads/technique that are used.

Now:
This may not be the most correct answer to your above query.

However:
I also wanted to take this opportunity to just stop by and say:
-Hi ol'Buddy!...It's been awhile since we talked.
-Happy Holidays!
