Re: (ET) POR-15

Guys,
For some time now I've been reading about some of your praises of POR-15, and figure maybe it's time I butted in and mention what should be a better product.
Besides old ET's, I also mess with old cars, like a '53 Studebaker Coupe for one. And one thing old Studes were good at was rusting. I subscribe to a monthly publication called Auto Restorer, and back in late 2003 they did a piece on a four month long evaluation/comparison of POR-15 to a product called Rust Encapsulator. Rust Encapsulator is from a company called Eastwood out of Pottstown, PA. This product was shown to be superior to POR-15 in many ways, especially rust protection due to creep.
Besides that, it's UV resistant, prep consists of removing most of the rust with a wire brush, cleaning with ordinary lacquer thinner, thinning with the same for spraying, and no need to top coat. But you can paint over it with just about any type of paint you might want. The POR-15 product requires two special pre-treatments and a special thinner for spraying. It then needs to be top coated if it's going to be exposed to the sun.
Both products cost about the same, around $100 a gallon, but you don't need any other special products with the Eastwood product. You can check out Rust Encapsulator at www.eastwood.com and investigate their stuff for yourself. It also comes in aerosol cans at about $20 for a 16 oz can.
As a side comment, any mower deck that I rebuild in the future will be sandblasted and then coated on the bottom side with the sprayed-on Xtreme bed liner system (www.extremeliners.com) and Rust Encapsulator on the top side. My local Xtreme dealer can adjust his system to produce a relatively smooth surface as opposed to the normal rough surface associated with most sprayed-on truck bed liners.

So Chris,

Neither my local hardware store (O'Connors in Billerica) nor my local
autoparts store (Bedford Auto Parts) stock POR-15 (nor had the guys heard of 
it), so I've looked it up on the web.  The Porstore site has all kinds of
instructions that lead met to believe that it's a lot of work to use this
stuff - soap wash, phosphoric acid wash, humidity control - but you're
suggesting it should work well without much ado.

Should I just get a pint or a six-pack of 1/4 pints as someone suggested,
and brush it on?

Did you use the regular POR-15 or the two-part Hardnose(r) paint?

Joel

Subject: (ET) First snow report from the blower



Finally had the first snow here in MD. Some thoughts on the blower with
POR15 and the 26ah aux battery pack:

1) POR15 is God. Or close to it. This is powdery snow that usually
accumulates in the chute. Tonight, there was NOT ONE BIT OF SNOW IN THERE. 

Painting the inside with POR15 makes it slick as glass. No, greased
smeared glass. The snow literally has nothing to adhere to, so it just
falls off if you try to press it on.

I would strongly recommend that everyone go out, get a little can of
POR15, and paint the inside of your chute. Think exceptional. Think no
more wax.

2) The battery monitor is a good thing. That one battery is still low,
it's pulling it's light on when going up hills in L. Not good. Still,
I'm glad I have the light to keep the load off the battery. Will replace
it in a week or two.

3) The aux battery pack (3 26ah Hawkers, connected via the accessory
port) works wonders. The massive sags are reduced and buffered, and I
was able to plow the driveway with no problem. I think AGMs in parallel
with the T105s are a great idea. In the weight box now are the 3 AGMs
(with 40amp fuse), and 4 more that are not hooked up for power but
provide ballast. I'll put another string online next week.

4) On charge the Elec-Trak seems to pull about 1,000 watts, with a power
factor of .92.

Chris
