Kitty hair, JB Weld or Polyester Filler?

I messed up and took off too much material when grinding off frame tabs. Nothing terribly structural but I need to make it look nice before paint.

What are suitable options to smooth and how do I get tubing looking round again where it’s got some flats?

I like epoxy with a featherweight filler, makes it lighter and easier to sand. Direct to clean, bare metal.

Bondo works, too.

Just remember you can't powder-coat most fillers, in case you were heading in that direction.

A friend of mine uses Lab Metal for non structural repairs. http://alvinproducts.com/

The lab metal stuff looks interesting and can be powder coated but I’m painting the frame so no worries there.

My biggest concern is how to form any material into a tube shape and sand it back.

I was thinking maybe a piece of pvc cut lengthwise and sandpaper within it to sand but I’m still not sure how to apply any product onto a tube in a tube shape!

Just rough it on with some kind of plastic squeegee, get it as close as possible and then sand it back to round.

are you needing a tube put back onto the frame? I am confused.

overfill it then sand back by hand.
A pvc pipe with sandpaper stuck to the inside isn't a bad idea, but it's not too tough to do by hand.
