If you grind through everything, how do you know when you've hit SMC? Is it grey?

The SMC in the hood is white. And the primer/sealer/whatever coat (at least, on mine) is black.

Hmmmmmmm.......... I went through the black coat in a couple places, and came up grey. There's absolutely nothing underneath the grey.

OK, so maybe it's not perfectly white... like greyish-white. Anyway, yeah you sanded through to the SMC.

I think I need to take a pic... there's no way you could confuse it for white, it's like a dark-medium grey.

If you keep sanding you will find the air layer.

To Ryan: Huh, that's odd. Can you take/post photos?

LMAO !!

So then the only thing past that is the $%^%@$#@ layer, right?

Be careful on the corners because you will quickly sand the corners right off, and the base material on the hood is white. I practically ruined a hood this way. The corners can be repaired but it's a pain.
