Just wanted to see what the DIYers use to get the scale and old paint off the metal. Wire brush? Sander? If so what grit? Thanks in advance

 

i think the most common thing is one of those little 90 degree hand grinders with 2 inch scotch brite pads .. but i personally dont remove old paint if it`s good .. just fix the bad places ..

 

Thanks would you recommend replacing the front rails when removing the floor pans or just cut around them if possible? Could I just cut the rot out the grind down the old welds to preserve the rails and seat boxes? Thanks again
