This thread was created to warn others detailers, novice, experienced, and even the pros.


So I was working on a new Honda Element last Sunday, only very minor correction needed. The plan of attack was to use M205 via the Flex and a polishing pad. There was however a few RIDS that needed M105 and the rotary. The front of the car also had some sort of white over spray on it and since I had my rotary out I thought I’d try and remove what the clay had not. I was running my Makita on a speed of 2 with M105 and a PFW pad. I applied medium pressure and with in seconds the paint wrinkled!!! :eek:


Yes, even someone with 20 years experience running a rotary can mess up now and then…just sucks it happened to me.:(


I’m really kicking myself in the butt over this one because I had seen the warnings in threads before about this so called “paint wrinkle”, which can occur when polishing plastic bumpers with a rotary buffer. I honestly didn’t give it too much thought since I have been doing this for so long and have never had it happen to me before.


In talking with others it seems that the flex agent added to the paint for plastic pieces, makes them much more susceptible to paint wrinkle. I’d more inclined to say it’s more of a problem on the newer cars, since I’ve never had this happen before, but I really can’t say for sure…paint really has been changing a lot over the years as the EPA clamps down on auto manufacturers.

For those who are wondering, I dropped the vehicle off this morning to have the bumper cover repainted, and the owner should have it back sometime tomorrow. My father works for one of the elite body shops in the twin cities, so the car will definitely be in good hands.;)


I’d also like to say that the owner has been very understanding with this whole deal, which definitely makes things a little easier on me. I also feel better knowing I haven’t lost his business and that he still wants me to do his wife’s car and has also referred me to some others.

ouch.

This just confirms my paranoia in only using the PC on bumpers is well placed hehe

I am glad for you that the owner was cool about it.
 
Well no more rotary for me on plastic bumpers. Thank you for showing what everyone was talking about.:iagree::whs:
 
Wow! It almost looks like the paint hasn't bonded with the plastic.

Glad your dad works in an auto shop and that the owner was understanding!
 
Paint doesn't stick to plastic very well, its starting to peel off of my 03 Jettas bumper in one spot where a rock started a chip. Very annoying.
 
You know, I recall reading last year on the Zymol website about some sort of wax they have especially for painted plastic areas that preserves the "flex" of the paint.............

Just thought I'd add that :D
 
that wax is probably outrageously priced to boot.
 
That wax is only $20 for a little pot.

Paint does not like to stick to plastic thus you use adhesion promoter to change the polarity of the plastic before painting but even this can not create a nice bond. Have to be careful as when you head up those bumpers they get soft and so does the paint and adhesion can be lost very fast.
 
That pic looks more than a paint winkle. Looks more like a repaired area gone bad. A paint winkle on a plastic bumper looks like the phrase states, paint winkle. This is deep and cracked. Let us know what your Dad thinks about that defect.

:whs:That doesn't look like a normal bumper underneath. Kinda looks like someone used some sort of filled in a past repair, then painted over it.
 
I do have to agree, it doesn't quite look like what you'd expect with a paint wrinkle but he did say that it was a new Honda Element....could have been repaired by the dealer before being delivered though if some damage was done during transport.
 
I agree that paint looks a little on the thick side but it was the OEM paint.

Another pic that the owner took.

Who said it was OEM paint?

Vehicles getting damaged in transport and during unload is fairly common. The dealer repairs it and never tells the purchaser. The owner thinks it is factory paint when it isn't.

I do paint and body and detailing, and to me, that looks like a repaired area, not just paint wrinkle.

I did, the body shop did, and the owner confirmed on Autopia that he picked up the car as it was coming off the transport.

My father owned his own body shop for 10 years and handled all the work for the local Dodge, Ford, and GM dealers....I'm well aware of how often new cars get damaged and fixed without the owners knowledge.

Thanks for sharing your experience with the forum Rasky, there's an old saying that goes like this,

"Try to learn from other people's mistakes because you might not live long enough to make them all on your own"


Same thing happened to me one time buffing on the front bumper/valance of a Viper at a Viper class with about 30 people watching. Ouch!

We carefully sanded the clear flat and then carefully buffed out our sanding marks and fixed it but everyone watching and the guy doing the sanding and buffing were holding their breath the entire time.

:D

Would this have happened if you were using a DA?

This has happened to people with DA's. Mostly with hot paint on a bumper or trim piece. There is a thread where it happened to someone with a DA.
 
I seen it happen on a new 911 about 8 years ago. Had a small scratch on. The detailer took a rotary to it and burned the paint to a wrinkle like that. Had to repaint the bumper. Those plastic bumpers do not adhere paint well.
 
is this why u should tape the edges when using a rotary? is this just an example of getting too close to the edge?

im sorry this happened to u. good job taking care of the customer and making it right!
 
Thats just plum crazy! Kudos for stepping up!

Thanks for sharing!
