3 " 0r 6' sanding disk????

Well if the choice is 3" or 6', let's just say with a 6 foot sanding disk and a whole pot of coffee I'm going to end up with a convertible!

Just kidding, 3" or 6", I'm gonna say it depends on what you want to sand. Match the sanding disk size to the panel you want to sand. Keep in mind sanding edges it's going to go through much faster than flat panels.

If you're sanding large flat panels 6". If they are smaller parts 3". Maybe you need both. It really depends on the car itself and how much of it you need to sand down.

you really need to explain on what you are sanding. If just going by what you posted i would say go with a 3" because it can get into smaller areas however it will take longer to do bigger areas. I only have experience with headlights so the best grit for me is 1000 OR 1500 followed by a 3000
 
I would be removing sanding scratches,pigtails,key marks,and deeper scratches that buffing will not remove. Maybe orange peel after some practice.

I would do those by hand. If you have to sand a whole car down quickly then you probably need both 6" and 3". 6" to do the large flat panels and 3" for the smaller areas.
 
i would opt for 3"

A and B pillars, curves before body lines and the small flat surfaces of bumpers before an edge lead me to vote for the 3"

the 6" is a great time saver for large realestate areas of the hood, roof and doors, but the 3" will be used just as much.

that all depends on what the paint / clear / scratches you're working with.

have my mind on a few other things at the moment, but i think my selection includes...
-4000
-3200
-3000
-2500
-2000

I believe the autogeek store has the disc in stock now. might call and speak with one of the rep's, but like i say; it's really dependent on what you're working on.

Interestingly enough, whenever I've had a wetsanding project here at Autogeek the most popular sander is the Griot's Garage 3" Polisher with #1500 and #3000 Unigrit Finishing Discs.

You can EASILY control this size of a tool while it's sanding even near edges. Not true with any of the larger air or electric tool.

Look at the pictures in these two articles...

If you're going to do any machine dampsanding, be sure to get an interface pad to go between your backing plate and your sanding disc. This helps to make the sanding action smooth plus the sanding disc can more easily conform to the surface.
