Sandblasting what a ******* mess. Spent 8 hours scouring the insides of these rails to clean bare steel. Got about 95% of the corrosion out of there. Going to epoxy prime it tomorrow to seal it up, then take a break from it. My body hurts after today. Still will have to blast the trans crossmember, forward framerails, firewall and engine compartment. Will need to get it done before the summer hits and its hotter than hell out there.
