Re: (ET) painting, using Extend

FWIW, I used Extend (brush on) on a few places on a car, many years
ago. After all the time and effort I spent trying to get rid of that
rust, I was really PO'd to find it was back--under the paint--just a few
years later. It was at that point I spent considerably more money and
bought POR-15. Now, wouldn't use anything else. YMMV.
I've used Extend, both brush-on and spray, on some heavily rusted
metal doors. It looked good for a couple of years, then the rust came
back. I hate wasting time like that.
Last year I sand blasted the underside of my EGT 150 mower deck. The
rust was pretty bad, and not all was removed by blasting. I wasn't
worried because I was going to use POR-15. They make a big deal about
how its low viscosity allows it to get down into all the microscopic
voids in the rust and encapsulate it.
Nice idea, but bogus. After removing the expected layer of dried
clippings from my beautiful POR-coated deck I found many little specs
of rust poking out through the coating. Granted, leaving a painted
steel panel covered with a thick layer of wet grass is a pretty
extreme test, but POR-15 is *not* the magic bullet some believe it to
Now I have to figure out how to hose down my deck regularly without
harming my motors. It's a mid-mount deck, so that's a pain. I'm
tempted to pull the motors and replace the bearings with sealed
versions just for this reason.
