POR15

Update: started working on removing the rust today.

question: do I need to take the pitted surface down flat to bare metal? Or what I have good enough to move on? See pictures. All scaling has been removed.

My car was blasted and epoxy primed inside and out. There was some residual factory "Pooled" primer in some of the valleys of the floor, but not like you show here.

I coated the entire floor again in POR15 just to be safe!
