Damp sanding with a palm sander da...

What orbit is best...3/16",3/32",or 5/32" on freshly applied clear?
.

Traditionally a 1/16" was considered aggressive but now days 5/16" is considered aggressive and 3/16" and 3/32" would be considered finishing sanders.

I think Meguiar's changed this when they introduced thier Unigrit Sanding Discs to work with all the popular electric DA Polishers because they are all 5/16" orbit.

If you haven't read through my article on this topic, (not scanned but read), take a read-through as it's incredibly detailed.

Damp-Sanding Tools, Tips and Techniques by Mike Phillips



Here's an example from the article...


Meguiar's Unigrit Sanding Discs - 6"



Meguiar's Sanding Backing Plate #S6BP 6 inch
Back side



Working face side



Meguiar's Foam Interface Pad #S6FI 6 inch
Back side



Working face side


Approximately 1/2" thick



The backing plate attaches to the Free Floating Spindle Assembly




If you choose to use the interface pad, the "M" logo attaches to the face of the backing plate. The "M" side of the Interface pad has the "loop" material while the face of the backing plate has the "hook" material.



The loop backing on the back of the sanding disc attaches to the hooks on the face of either the interface pad or the backing plate.

You failed to mention what a palm sander with a 5/32" stroke would be considered...I assume a finish sander so if I am right would this be a better or worst choice then a sander with 3/32" orbit?

Fresh applied clear coats!
