The Doubler made all the difference on something as stiff as Bondo.
Otherwise the bag is likely to split.

I haven't tried it with dry micro yet.
Just haven't had a need yet.

But the bondo bead was so neat it's gotta be worth a try...

Making the mold I needed a radius corner on a plywood form.
I've used Bondo for this before - but what a freaking mess to clean up!

So I dumped the Bondo in a reinforced Zip Lock bag (duct tape doubler
over the corner to keep the seams from popping open) and squirted the bead
out like cake decoration.

Then ran a tongue depressor down the bead to form the radius - and it
was DONE.

Came out pretty nice too, I think.
