painting sub frame (por-15) how much do I need

[Moose]

No its not covered in rust. Its just has certain spots. 90 % is painted with the paint flacking in certain spots. I've sanded down all the spots I think will give me trouble.

I just did a hole frame rear end and floor pans with 1 1/2 quarts.

So I would say get a 1 quart and you will be set for a front sub.

Oh yeh your finish product will be based on your prep time.
