I am not VERY happy; at the bottom of the can of filler is some kind of crunchy, rocky mess that is pebble like that totally messes up the blending of the filler.
Will have to write to the MFR... I have never seen this in a can of filler before?
Nothing like having grit in your filler when you wish to apply a smooth surface layer![/color]
Ah, that high grade filler with the Mustang on the can, that shows a guy getting show quality results with Bondo and a spray bomb.

I'm used to getting the stuff with all the resin on the top, where you have to mix the hell out of it, where the bottom of the can is harder. Never had it rocky as of yet though.
Usually the stuff is pretty good for a so called lower grade, and they have all become so expensive. That brand actually sands pretty well, compared with some, especially considering cost. I preferred it to many more expensive brands. I commend you for using body filler and getting good looking results, as it can be difficult to get it to feather out on wood, without flaking at the feather edges. I would consider Urethane (often yellow in color) thick primer. Toward the end of my autobody career, (one of my many tangents

) I started using it, as you can build it up to 1mm thick, while having minimal shrinkage over time. It sands very well also. On large panel repairs, you could fair in filler repairs to a perfect flatness, using 100-120 grit on an airboard.
When I first got into rc flight, I glassed and bondo coated a Dumas Cabin Cruiser with Bondo brand. I became so interested in flight, that I never got around to sanding it. I wonder how easily the bondo will sand, after 7 years?
