Here is a before and after shot of my floorboards from the grinder... there are still some dark spots in the boards... which Im assuming is deeper rust... when have I done enough to spray with rustoleum and put an end to my misery? Dont want this **** EVER coming back... The white haze you see in the after pic is the rust acid stuff dried... which helped... but there is still some dark stuff, which is somewhat noticable through the white haze... its worse once I took the grinder and got the acid residu off then the pics show... FYI... the darker spots NOW resemble a similar pattern to the lighter spots in the first pic... if that helps.

 

use por 15 instead i swear by that stuff

 

I know... but I cant get it this weekend... and want it back together this weekend... or I would... trust me... I sware by it myself.
