Does CC oxidize?

Clear coat does not normally oxidize the way single stage paint does .

9 times out of 10 if a clearcoat is extremely scratchy cloudy and dull looking it is clearcoat failure and buffing will not help it but further along the deterioration and will start peeling up shortly after .

As Tod mentioned sometimes a crappy clearcoat paintjob will die back and look dull and can be buffed out as in Lusters case senerio .This is not normal for a factory paint clearcoat

Mikes clearcoat problem was probably not the clearcoat oxidizing but most likely from fallout sitting on top of the clear causing paint damage sitting on the top of the paint from not washing and neglect.

Single stage paint will oxidize even though you keep up with regular washing .

I hope that explains it . Single stage paint and clearcoat paint are very different in that cearcoat does not normally oxidize with regular washing where as single stage will .

That's a good explanation, since the car was definitely not cared for at all. This car sat outside every day of its life, was rarely if ever washed, and never had any kind of protection on it. It was during a time when neither one of us really knew or cared how to maintain a car's appearance. The damage buffed out easily and has not returned.

Thanks for clearing this up guys!:Dancing Dot:

Thanks Flash! I actually joked around with her about playing Tic Tac Toe on it. Her response was something along the lines of "Ha ha ha. Now fix it."

Givem Hell DetailChick :sarge

I don't know if there is a right or wrong answer to this question. I have experienced this before on clearcoat, but didn't stop to try to figure it out :-?

There is certanialy something going on there I just don't know what. I do know if you would have let it sit that way for another year or so, you probally wouldn't be able to correct it. I think the important lesson here is that you both were able to save your finishes and thats just splendid news @-)
 
I've read several times that the top 30% of the clearcoat provides the huge majority of UV protection and I think UV is the culprit i.e. higher energy light rays that, over time, breaks down the polymers in the clearcoat compound (paging TOGWT!). That also helps explain why wetsanding to remove orange peel is not really a good idea and jeopardizes the long term life of the clearcoat.

Just passing on some info I've read over the past few years on different websites (and we all know everything you read on the intrawebby is true).

I do think the logic of the paint quality affects degradation over time as well. Just like everything else, there's most likely good paint and less "good" paint.

OMG Flash Im not giving anyone hell LOL i hope you were kidding!

im having an issue myself with a BMW black clear coated hood 13 years old that went flat/cloudy that a customer wanted me to see if I could buff out.

She was a zaino enthusiest and used zaino for several years then switched over to meguires and said thats when her hood went cloudy, after she used meguires.

I explained to her that we could try with no gauranteed results and also told her her hood may be beyond repair and need painting.

Well with much effort and heavy compound on a rotary her hood did buff out and actually got it to look pretty nice . But I was still skeptical how it would hold up and let her know too it could go flat again in a couple months.

fast foward to today ( 3 months later)and I was working next door and asked how the hood was , she said great ! Then she asked if I could detail it again so when I looked at the hood sure enough it had started to look cloudy again but not quite as bad.

To my surprize I got it to polish out again with M105, M205 on a DA! Go figure ! What will happen 3 months from now I do not know?

Anyone ever had a zaino problem like that before when another product was used on top?

Yes, I was just yanking your chain <:-P

I also have a customer with a 90's something 3 series. It is red in color and fades out after about 6 months. I polish it, and it looks good as new again. I have no idea what the issues is, just how to fix it :-B
 
OK Flash Ill be yanking your chain when you least expect it , payback :clap:

The red single stages really oxidize more than any other color I think .
I just buffed one out last week but only had to do one side because thats the side the sun would shine on every day . The other side was fine!

Im curious too how long it will hold out as its not garaged.

Puckman ive read the same thing (about UV being in the top layer) , probably read at the same place.LOL
 
Isla take a look around the light. It looks to me like the clearcoat has already started to fail and is peeling off. Although I could be wrong .

thats what it looks like to me anyway.

I still say clearcoat under normal conditions should not ozidize.

It can appear oxidized if it is exposed to harsh chemicals or fallout but really it is paint damage and not true oxidation.
