Re: (ET) painting, using Extend

["harry landis" <hlandis hotmail com>]

As I mentioned once before, something I tried last year worked out fine-I 
took all the pieces off my deck and had it and the pieces hot dip 
galvanized. So far, it looks just like when it came out of the dip. I never 
wash it or do anything else to clean it. Way too lazy.

Hi Thon,

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
be.

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.

Chris
