How To Wetsand and use a Rotary Buffer

How To Wetsand and use a Rotary Buffer (http://www.autogeekonline.net/forum/pictures-saturday-detailing-101/56195-how-wetsand-use-rotary-buffer.html)


In my detailing classes I share the correct techniques for hand sanding major flat panels as well as how to machine sand using 3M Orbital Air Sanders plus the PC style DA Polishers including the 3" Griot's Garage Mini Polisher as a dampsander.

We use both 3M Trizact discs and Meguiar's Unigrit Finishing Discs in 3" and 6" sizes. After sanding I show how to use a wool pad on a rotary buffer with Meguiar's M105 to remove the sanding marks followed by Meguiar's M205 to remove any holograms left by the wool pad and the M105.

I also show how to use DA Polishers for the final machine polishing step to ensure a swirls free finish on any type of paint with both Meguiar's M205 and Menzerna SF 4500


Here's some shots showing busy, hands-on training and practicing...


Here's Audrey showing the guys how to machine sand using the 3M Orbital Air Sander

Audrey has never machine sanded before so after this class she's going to be able to talk about the topic intelligently and she's going to know what she's getting into if one of her customers asks to have their car wetsanded.

Perfectly making overlapping passes with a quick arm speed...

Now she's using the Porter Cable 7424XP to do the same thing but without having to manage an air line under pressure trying to control the sander.

She has the technique down but says she finds machine sanding easier and faster...

Frank's turn...

Since I already buffed with the pad it needs to be cleaned first, so I show Frank how to use a steel pad cleaning spur.

Perfect...

Because of the size this tool is very easy to control and that makes it easy to sand close to edges or in tight areas...

Clean you pads often
It's so important to always be cleaning your pad to remove both the paint and the used-up product off the face of your pad or buffing will become more difficult, less effective and wipe-off of residue will become gummier...

That wool pad looks like a blast from the 80's in size compared to the smaller foam pads of today.
