PFarber, I think that's a bit misleading.
I've had the Mollasses work in a week on a tail gate that was just 'rusty' as in surface type rust.
If time is important to the job then blasting is the way to go if Time=Money... But if Time is greater than Money, not so much.
I found paint is softened up and anyplace the paint was scratched and leaving access to bare metal that the paint and rust were loose and treated. Anyplace the paint was not lifted still had clean white metal under it.
Yes I still had to finish stripping the paint but it was MUCH easier than before the 'soak' and the ROLOC strip disks worked great on the left overs which was cheaper to use than my compressor and Blast cab and to my surprise faster than sand blasting from scratch.
An application of Ospho after strip disk to get the pitted and difficult area's easily took care of the rest.
It took longer by the calendar... but I had less time and real money into the job. That's a Win in my book.
And incase others missed it... The Coke Shake was a JOKE!
