Proof of Rotary Burn

[thinksnow]

Inattention and a cavalier attitude lead to this debacle. I had just received my Zaino and my father wanted his car redone. Thus, I was more excited about my new LSP than the process to get there. As usual with me now, I compounded with Menzerna PG and followed with FPII.

Here comes the inattention part. My father is a runner, and *always* ties his shoes with his foot up on the rear bumper. I was taking out the numerous deep scratches with the PG, a cutting pad, and the rotary at 900rpm. The problem is, I was watching the scratches to gauge progress and not watching anywhere else.

This is my prize for stupidity:


No redemption from the Autopia community expected, but for 156K miles, she doesn't look half bad.

I have some paintscratch.com tri-color and clearcoat on the way, so I'll get to showcase the before and after of the kit. It's on the plastic, so I assumed Langka would not work in this application. Plus, I read a few threads that suggested that Langka only works with lacquer paints. I'll do a dry run with just the kit and go from there.

Kids, PAY ATTENTION when using the rotary. Let my confession breathe new life into your healthy fear of the machine. I feel better getting this enormous embarrassment off my chest

I am going to go out on a limb and say the top part of the bumper must have been very,very thin. I know the rotary can burn paint but at show a low speed you would have to be on it long enough for you to realise you are doing something wrong.

I've done 2 cars so far with a rotary and only managed one tiny burn on the edge of a door handle. It seems that all plastic parts (handles, bumpers, etc) are very delicate and extra care must be taken.

I know I've learned my lesson.

My thoughts exactly to both of you. The plastic rear bumper paint feels pretty soft--thus the low speed. It doesn't matter if you aren't watching the edge of the pad, though

Thanks for the warning. When I finally get a chance to use my new rotary for the first time, I plan on using it at about 1000 rpms and then use only a polishing pad and Meguiar's #3 or #82. For sure I am staying away form all edges, door handles, bumpers, etc. I'm heading for just the big flat panels and everything except those panels will be be taped and covered.

Those plastic parts have a problem with heat. It's not necessarily the agressiveness of the product or even the paint reaching it's burn temp. I think it's the surface below reaching a temp that makes it too soft.

Both Jason, for those who remember him, and myself have taken paint off that type of surface before with a rotary.
