Would the Must For Rust , mp-7 product be fesiable in an applicatation to an existing metal building?  Because of a high humidity problem the purlins are rusted so bad the depth, of the rust, can nearly be measured with a ruler. Can this be sprayed with an airless pump are you a supplier   Lots of questions: cost, coverage, etc.!!  Hope to hear from you.

The Tinman Respondeth:

This product will spray well, and is available in 55 gals, if necessary.
Coverage is just like spraying with water, but you may need 3 or 4 applications. 

Soak, wait, soak, wait, and sooner or later you will win with this stuff. It is the best.


NOTE: MP7 was bought by another company and the name has changed to
Must For Rust , or MFR as we call it. It is still great, effective, easy.
