Burning Paint with PC 7424

[T Riddle]

The surface had something on it that caused the paint not to bond to it when it was paint. Most paint burning you will see will burn through the layers....that just grabbed all the layers and moved them over. Definitely a paint defect and the dealer will probably fix it no problem. You can just tell them you noticed it while washing.

Sorry!! I brought this old thread up as a link to the thread about polishing a bumper w/a DA. Purpose was to show that damage can still occur w/a DA.

I was looking for this thread to do the same but couldn't find it. :xyxthumbs:

I can't believe the amount of people recommending the OP to lie to the dealership for something that was caused by his error. Man up, learn from the experience, and move on.

i have purposely burnt paint with a rotary to show people i was training what it looked like and have never seen that happen before. like alot of others here i am thinking that paint did not bond and cure fully

That really scares me to purchase a DA now... I thought you couldn't burn paint with a DA! :awman: This obviously proves it wrong.. *sigh*

In a world where it seems as though just about anything can and will happen I still feel that burning your paint with a da though possible is highly unlikely. It would be like burning your house down with a magnifying glass though it is possible if you held it in the sun and focused the concentrated beam of sunlight on only one place for a very long period of time. Sort of like running your buffer on 6 and really leaning down on it while you kept it in one fixed position on the paint. Heck if you rub two sticks together long and fast enough you will get fire.

The picture showing the gathering up of paint and burn thru seem to be two different animals. On pratice hoods that I have burnt thru the paint with a rotary and a woolpad on purpose ,it looked as if it was sanded smooth or in some cases ground down with a grinder in severe cases. The paint gathering up has been covered on other forums and personally I have not had this happen. Those that have posted about this seem to mostly have had this happen on plastic bumper covers or panels on factory painted late model cars. Most claim they were using a rotary and this is the first I've seen done by a DA. A lot of opinions lean to heat as a probable cause. As far as taking it back to the dealer,would you want to detail or paint a customers car and later have him do the same and come back on you and claim he was just washing it ? Paul S

Everyone you have to understand that burning paint on a metal surface vs a platic surface is totally different. It is the way the paint bonds to the surface and it was on the edge. I can understand why people would think it is not a burn because it bunched up. It is a burn, the paint was rubbed through in one section and then the pad just kept pushing it causing it to bunch up. Rasky1 even has a thread of this actually happening to him. I am sure if you look this up you will understand it was a mistake by the op, not any type of defect with the paint.

It seems the side of the pad dug into the paint and then it just pushed into a clump. This is what will happen on a plastic piece when the edge of a pad grabs the paint. Also the paint being hot from the start just makes it that much easier to wrinkle the paint like in your picture.

As in your above quote.I also think the pad dug in and grabbed the paint and due to the heat pushed or piled it into a clump. This is not what I relate to as a burn through such is commonly done on a seam or high spot. Thats why I see this as two differnt animals which are both operator controlled or induced. From body shop guys I have talked to about this problem they lean towards the idea the flex additive paint combo is more sensitive to heat then the rest of the car.

WOW!! I'm sorry I dug this up. I just wanted to show that nothing is totally fool proof. Granted it is less likely w/a DA. Message being that you need to be careful with anything, and not assume it can't happen.

I understand what you are saying but you will not see paint burn like a metal piece. It is going to go through the paint grab it and wrinkle it up because the paint does not bond nearly as well as it does to metal. I would agree the flex additive does play a role in the equation. My friend has a custom paint shop I do a lot of wet sanding and polishing for and we were seeing how different mixes work on the plastic bumpers for race cars, see what would stand up to the buffer and no matter what he tried they pretty much wrinkled the sameway.

Thank you. Rasky1 was man enough to admit to his mistake and post it online for the whole world to see.

Yes he was, and we a had a conversation before him doing that. Plus he wanted to show what happens when you burn a plastic bumber. It has happened to all us and I mean all of us.

You can cause damage even with hand when setting is right. Are you now scared from using hands? In other words: Every tool (hands included) has to be respected when used.

It is very likely under "right" circumstances so if I were you I wouldn't be betting bumper of my Porsche on it.

P.S. It takes only seconds to start fire with magnifying glass and sun when circumstances are right.

I think what you are trying to say is- It is very likely under the WRONG CIRCUMSTANCES.

By that I mean, for example, if I were to allow my black Porsche to bake in the sun for several hours and then proceed to use my buffer on the already hot paint the likelihood of my burning the paint would most certainly increase. If I over worked the product to the point where I was dry buffing the already hot paint I am sure that likelihood would certainly increase even further. That likelihood, of burning my paint, would definitely become a certainty if I chose to buff out the bumper of my Porsche by running the buffer on speed 6 and applying a lot of pressure while at the same time keeping the machine staionary and not moving.
The point that I am trying to make is, as you have stated earlier, that you have a responsibility to understand what it is that you are trying to accomplish and you have to develope a respect for the capabilities and limitations of the tools which you choose to work with. With that said and some common sense a person should not have any reason to FEAR using a DA polisher.
I myself fell victim to a lot of needless and unfounded fear mongering which caused me to not use my Flex 3401 out of fear of inflicting buffer induced paint damage to my Porsche. The time that I spent fearing my Flex was time wasted. Fear is something that should be reserved for the unknown. With all of the detailed postings and threads by the likes of Mike Phillips and others world class professionals on this forum there is no shortage of knowledge and therefor no need to fear. IMHO

You are right that person should not be afraid but at the same time person should never become overconfident / falsely confident either. Both are wrong and person doing something should keep truth in mind when doing it.

Truth is that you _can_ damage the paint with DA when circumstances are _right_ (my knowledge of English is ESL, from what I know when all circumstances for something to happen are there then circumstances are said to be right, not wrong, please correct me if I am wrong).

Those that forget that / ignore that / never knew it are much more likely to end up with damaged paint even with DA than those that keep it in mind.

And even those that keep it in mind and have many years of experience can make a mistake, or be distracted for a moment.

How much does it take when those circumstances are right? As little as seconds. I could illustrate that on the bumper of your Porsche as long as I am not held accountable for it.

Being afraid is a mistake. Being fearless is often synonym for being reckless, which is a mistake too.

Your English is fine I was just making a play on words. I am glad we both are in agreement about fear. Not being afraid is not synominous with being fearless. Fearlessness is more akin to recklessness and I never suggested for anyone to be reckless. I think we are in general agreement so rather then getting into semantics let us just say:nomore:
