Here's what this well respected member from the autobody101 forum does to finish cars:



800 grit dry by hand

1200 grit via DA

3M Super Duty compound with grey foam pad

Zymol liquid (Turtle Wax)



DONE!!!!????



Can you name all the things he did wrong??





What him go at it and just :think2 :cry: :scared: :nono :angry :soscared: :shocked :confused: :nervous2: :think: :hide:





The Video you have been waiting for!
 
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%.
 
Here's some more of his quotes in a discussion on clear coat scratches:

All you need is 1200 or 1500 from 3M,,,,,that's it! You don't need all of those 2000-3000 grits. Your waisting time and money.

I have done it both ways. I find that for me it is MUCH easier to buff after I go over it with the 3000 on the da wet. I have buffed right after doing the 1500 dry but I have I think it takes me less time to quickly go over it with the 3000 and then spend less time buffing.

Sounds like you need to change your compound then..................

Old Dupont Guy said:
Quit sanding so much and change something with your buffing, or the compound you are using.



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?
 
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.
 
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
 
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.
 
Funny I am reading this topic. I got back from Meguiars advanced training course. They showed everyone how to sand and buff a panel. This guy in the video is doing just about every step wrong and making it worse than the orginal condition.

On a side note, I tried the Meguiars M105 on a properly sanded panel (4000G Abralon) and 90% of the defect came out with 5 passes. What an amazing product.
 
That was painful. The worst part is all the guys on that forum think he is a god now and will take his word as gospel. I don't even know where to start.........He seemed like he was sanding too aggressively, he used too much compound, that pad looked worn out, he didn't even remove the compound residue before he applied Wal Mart Zymol to the paint with what was probably a cheap bath towel, and he didn't take his jewelry off.



Edit: Oh, and he didn't follow up with a finishing polish.
 
Your right frito. that pad was trash and far too much compound. I would of applied two drops of menzerna to that area

Oh and except for ultrafina, 3M polishes are horrible
 
Damn! Did he just use dry sandpaper on a dry surface? Oh, and I love how he dusted off the area with his hand with that big *** ring on his finger. That gray pad was trashed. So let me see, he was smart enough to at least wet the gray pad before using it (with all that compound) yet he dried sanded. Love those low quality towels. Someone please hit that guy.

Have you tried 3m 3000 RC? It removes sanding marks that other compounds won't touch.
 
Sad but i think his name says it all "Old Dupont Guy". I think in the back of autobody guys minds is they can reshoot the panel if they screw up, so they take the most aggressive approach. Where as a detailer takes the least aggressive approach.
