Question about UPGP Application

[Kurt_s]

I have once.

It is going to require more experience/practice, because for some reason I experienced a bit of streaking/hazing when I applied the OCW over the OS.

Like I said, this paint is very revealing and sensitive, and will show any streaking or hazing and make it stand out like a sore thumb.

Rob,
I thought that you said that OS and OCW were synergistic?

I would expect that the clear coat on your HHR would be the same as for other GM paint colors and it would not be related to the paint itself. Did you use anything (car wash, detailer, etc.) after the OS step and before the OCW?

Maybe you just notice the streaking more with that color?

I'm only trying sealants again after being a nuba guy for many years, so I am not a sealant expert by any stretch of the imagination. With the nuba, I used a very repeatable process that worked well for me. I always used a final glaze before the base coat of wax, and both the glaze and wax were of the same brand. Mike P has commented a few times about how products within a line are made to compliment each other. As I read different threads about how some like or dislike products, I keep wondering if there may be a connection.

Before I chose WG DGPS3.0 in late December, I read a number of comments about the importance of surface prep with some sealants. I used WG FG3.0 before applying the sealant which worked well for me. When I use other polishes, I wipe down the paint with IPA before using the LSP to check the level of correction and remove polish residue.

I think that Zaino was one sealant that was particularly noted for requiring a special cleaning step. I sort of remember reading other comments for other sealants including Blackfire. I also found Richard's recent review of Liquid Natty's Blue where it didn't produce good results until after he used a different paint cleaning and preparation process to be interesting. Supposedly, OS can be applied over other waxes and sealants and will bond under the old LSP. I really don't know if that is true or it's a forum rumor, but it could also explain your success with OS.

With a hazing issue, do you think that your experience with Blackfire on your HHR might be due to a paint cleaning step residue issue? It sure sounds like a little chemistry involved here.

When I applied the Blackfire Wet Diamond, I followed by normal process: I polished the entire car, did an IPA wipedown, and applied the sealant.

When I decided to remove the Blackfire, I also went ahead and did a chemical cleaning with Klasse AIO, and put the OS on top of that with what turned out to be very good results.

I do think there could be something to your chemistry theory though.

Rob,
I thought that you said that OS and OCW were synergistic?

Yeah, good catch! They always have been up until a few weeks ago. But again, I only tried it once and noticed the streaking/hazing that I mentioned. I need to give it another shot, as it would be nice to get the added bonus of OCW which adds a bit more depth.

I would expect that the clear coat on your HHR would be the same as for other GM paint colors and it would not be related to the paint itself.

Exactly. Which is what makes this all the more difficult to understand. But it does seem that different colors react differently to various lsp's.

Did you use anything (car wash, detailer, etc.) after the OS step and before the OCW?

Yes, I let the OS cure for a week, then I washed it with ONR. It was immediately after the ONR wash that I tried the OCW and got the streaking/hazing.

Maybe you just notice the streaking more with that color?

Well, the red most definitely makes every speck of dust extremely noticeable, *especially* compared to my silver cars, and to a lesser extent the bright yellow car I had as well.

That said, I do work under pretty good lighting conditions in my garage, and I always check at various angles looking for streaks etc and I had never noticed anything of significance in terms of streaking with OCW before.

Something has definitely changed though.

I'm also surprised at how dusty my car gets just sitting in the garage, which again goes to the fact that the red is so much more revealing. So yes, there could definitely be something to the red being more revealing.

I think that LSPs probably absob, shift, bend and/or disperse light wavelengths differently. Some LSPs seem to be better with different colors. We see reflected light wavelengths coming from an object, so I'm pretty sure that there are wavelength absorptions and/or shifts involved.

Silver is a great color to hide the need for a car wash. Red, black, dark blue and dark green seem to show everything. Maybe that's why I drive light colored cars now. Even after a couple of days, my cars still look good when I'd be out washing the dark ones.

I have two dark cars and they definately show all. But our kids are grown and I have lots of time to keep them up. When I had kids at home I never wanted dark colors!

Went to light colored cars after my son was born. Funny, my trips to the golf course diminished too. So sad...

I used ONR to clay lube my in-laws silver maxima this spring. I didn't notice any streaking.

Did you apply OCW to a hot surface?

Just to clarify, I definitely did not get streaking or hazing from ONR. I only got it from OCW.

....and no, I *never* apply *anything* to a warm surface, much less a hot one.

Chemical reactions, environment and technique are the three things that come to mind when having issues with a chemical (car related or other).

Don't understand why you would have streaking with the HHR.

Maybe the HHR's CC paint surface has a different surface chemistry than other clear coat paint? I did a lot of protein chemistry and played with different surfaces early in my career. Maybe the CC paint has a slightly different surface structure to handle the pigment additives of the red paint, hence the interaction is different than other clear coat paints?

Maybe a question for Dr. G or GM? GM used to have a great technical organization that would answer those kinds of questions. It might be a good place to check.

Ok, I used OCW again on my red HHR. I didn't have any streaking to speak of this time, but I was much more careful in how I used it.

I was careful to use a *small* amount. I also applied to a small section at a time (around 16 x 16 inches). Finally, I made sure that I had two MF towels, and I would wipe with the first one and then immediately follow that up with the second (drier) MF.

This seemed to have made the difference.

I have only had issues with OCW streaking once. It was most definitely my fault as I applied it to panels that had spent time in the sun. They were warm to hot, The reason I bring it up is that after the rainstorm came a short time later and then the car dried it looked good and the streaks were gone.
