Question about lead seam filler

GeorgeH said

I would smooth that down further with a 3 inch roloc disc or something even if it means using more reinforced filler. I don't like to try and push filler into lots of nooks and crannys like that and potentionally trap an air pocket that can blow out later when it gets parked in the sun.

Not enough money in the world for me to take a sanding disk to lead filler. Aerosolized lead dust? Yeah, no thanks. Breathe some of that in and you’re screwed. Get it on your skin and you can absorb it too if the particles are small, like they will be if you take a roloc disk to it.

That’s why you only use body files on lead. Bigger pieces, no chance of breathing it in or getting coated in dust. And clean up is easy, just sweep up the shavings. If you make dust it’ll get everywhere.

The surface isn’t as consistent as I’d like to see it, but metal-2-metal over what the OP has isn’t going to cause him any issues at all.
