[urq] Dipping vs Blasting

[Marc Salamone]

Hi Steve,

Thanks for the detailed info. Got any pictures of your setup?

The reason I am leaning towards the rotisserie is that I am most worried
about the underside of the car, and will need to strip off the undercoating
and blast the seams and anywhere there is rust. I figure that this would be
easiest/most safely done on a rotisserie. Also, if I get the pnuematic
casters, I will be able to roll the shell outside (gravel driveway) for
blasting and inside for stripping.

The rotissarie is only about $1100, so if I use it for multiple projects, I
should get my money's worth out of it. I may not strip the interior, but I
have not yet had a chance to make a detailed inspection of it's condition,
so we'll see.

Good luck with your project, and keep me posted on your
progress/discoveries. Best,

	- Marc
