Test: UTTG over PB-TR

[CEE DOG]

I followed up with the other test we've been discussing.
About 5 days ago I applied PB-TR to another bumper and let it sit a few hours before rubbing it down good with a towel. Today I wiped an area with a wet towel and then dried. After waiting a few minutes I applied UTTG over the taped off area.

The idea was to see if we could lock in the darkness of the PB-TR on this faded bumper with the use of UTTG sealant.

Well, it appears (second picture) that the UTTG just removed the PBTR and took it's place. We'll see what happens over time.

This is the taped off area before applying UTTG (Picture taken with the area shaded)

This is right on the tape line of the area just shown (Picture taken with the area in the sun) In the shade the PBTR side would still look like it does above.

That's interesting. When I applied UTTG over the PBTR it darkened the mud flaps back to their original color and gave them a nice gloss. Your bumper looks like almost the opposite happened. The UTTG side looks lighter than the PBTR.

Durability on the mud flaps has been good, after 1 week with 2 rains and constant outdoor exposure they still look good

I think the same thing happened on your mud flaps. The UTTG replaced the PB TR. But on your material the UTTG darkened it more.

Keep in mind this bumper was extremely faded. Much further then what you see on either side now.

I'm not sure about that one. I am going to treat the mud flaps with the UTTG only, after they have faded out again and we can see for sure. I hope you are right because it is easier to apply 1 product than 2 and the UTTG will definitely outlast the PBTR.

12 DAY UPDATE

Well, it looks like 2 rainy days really showed the PB-TR's weakness.

It also showed that laying UTTGP over PBTR didn't compromise the UTTGP.

However in my opinion ther is absolutely no point in layering UTTGP over PB-TR as I believe it does remove the PB-TR

I didnt like PBTR after rain. It ran on the paint.UTTG is a much more durable product IME. Megs Ultimate Protectant is a durable product too.

Jim, so does Meg UP darken the black plastic trim like PBTR while holding up like UTTG?

Kurt, unfortunately it doesnt IME. It is a great option if you prep the trim first. I love MUP on running boards. It is durable and isnt slippery!

I am a little confused by your pictures. In the first side-by-side comparison (at five days) you show "UTTG OVER PBTR" on the left and "PBTR" on the right. Then in your 12 day update you have "PB-TR on the left and "UTTGP" on the right. How do these match up exactly? From the 12 day update pictures it looks like the "PB-TR" side is trashed, as you can see it running or streaking, not to mention it looks significantly more faded. So is that side (left) the two of them layered together or just PBTR by itself? And what is the right side showing?

In the first picture you can see I've taped off a square and placed UTTG over the 5 day old PBTR. The 2nd picture is taken on the right side of that square. In that second picture (as noted in red text above it) it appears that the UTTG simply removed the PB TR and replaced it. So at this point we have UTTG in the square and PBTR on the rest of the bumper. There may be some trace of PB-TR left mixed with it but if there is it is inconsequential to the results we see in the pictures. If anything the PBTR would have only weakend the UTTG's bonding ability. I am actually surprised to see it didn't weaken it more.

In the 3rd picture we see the two sides after it has rained for a couple days. This 3rd picture is taken on the left side of the box we taped off. I didn't come in here and check the forum to see which side I had taken the picture on last time since I think I documented this is a way that makes it clear. Now that you bring it up I'll post another picture for you that I took at the same time last night. This should make it clear.

Thank you for explaining. It makes perfect sense now. And again, thanks for yet another interesting comparison. I will have to inspect the plastic bumper and trim of our Prius and see how it is holding up with the PBTR application I did recently. We have had a lot of rain here lately.
