I knew what was next since I heard "Nibs"
a disaster is not enough.

David, that is just too much. Sad thing is that 90% give or take body shops all do the same things and learn from one another.

I'll let someone else answer the mistakes. I do not want to spoil the learning.

Thanks for the laugh!

Try browsing the forum and read this guy's other posts - especially in the Color Sanding, Buffing, Polishing sections. Makes the noobiest Autopian look like a seasoned Pro.

"Zimoil or whatever you call it..."

Love it. That video just bumped my confidence in trying out the rotary by about 60%.

That man sure does love his super duty. I can hear the passion for the product in his voice.

Here's some more of his quotes in a discussion on clear coat scratches:

A good compound should not have a problem with 1500 sand scratch...............Let the compound do the work.

Is it me or between the sanding and polishing did he just grind way massive amounts of clear?

rydawg · 03-22-08, 07:35

David your killing me.

I knew just by watching the video. He is old school and you can not teach old dogs new tricks. He seems like is afraid of change also. He is also the type," If it is not broken do not fix it".

Sad part is that there are much worst out there.

ScubaStevo · 03-22-08, 08:08

I suppose if he put enough clear on the car, his process is fine, other than the fact that he didn't move the buffer off the same spot for about 30 seconds at what seemed to sound like 3000 RPM. lol

SVR · 03-22-08, 08:11

That was nasty. Why was he sanding?
The finish looked no better after
Now maybe with thick orange peel in the clear you would do some sanding but geez 800 then 1200. bloody hell

The whole trouble is that body shops are all for get it done quick and get it out the door whilst pro detailers and us extremists care about paint thickness, have far higher technology products and techniques and don't care how long it takes and want to achieve higher and higher perfection

Whats the difference between using 1200 grit sand paper and 1200 grit compound in removing deep scratches?

Huge. 1200 grit sand paper creates 1200 grit scratches, 1200 grit compound removes them. There is no comparison in cut.

Think FPII (2000 grit leveler) vs 2000 grit paper.
