Clean metal is easily handled with a sand blaster. Of course you end up
with sand in everything within a 100 yards. Hardest part is brush painting
the frame. Seems it took nearly a day to paint just the rear half of the
frame with POR. Can't believe how many nooks and crannies that take forever
to cover in paint. Another problem is getting compleat coverage. Even went
to the trouble of using different colors
for each coat and still missed covering in a number of out of the way
places.
I've got the same problem as you with getting things galvanized. Shipping
would excede the new price of most of the pieces. Keep us informed as to
how the stuff works. Zinc content means little if the stuff isn't bonded to
the metal. Beauty of galvanizing is that it supposed makes a chemical bond
between the steel and zinc so doesn't exfoliate and is self healing, to an
extent. A long term survivability test of the material is essential data.
Suggest you paint a couple of scrap pieces and then spray them with salt
water solutions on a daily basis, leave fertilizer or other corrosive
materials on some peices, and purposely scratch some pieces to bare metal to
see how the pieces react to the above abuse.
POR is great stuff and sticks tenaciously but my concern is how the stuff
will react when its nicked. Will it contain the rust to the nicked area or
will the rust continue under the surface hidden and protected by the super
tough POR paint film?? In defence of POR, its nearly impossible to scratch.
Outer paint coat on the rear crossmember was non UV reactive RustOleum.
Had a hard time getting the tub to fit properly so kept trying to move it
around, banging on things, etc. Since I was working by myself, hard to be
careful and as I got more frustrated, my concern for the paint dropped.
Ended up scraping off the black outer coat in a number of places but nowhere
did it scrape through the grey POR undercoat.
