#The major paint manufacturers like Sherwin Williams, PPG, and DuPont don't produce a POR-15 like product. This is thought to be because they couldn't possibly warranty such a product. | #The major paint manufacturers like Sherwin Williams, PPG, and DuPont don't produce a POR-15 like product.

*Can sandblasting "increase" rust? Or, if the rust is removed and the metal is sealed, shouldn't it be eliminated? Some thoughts on this are: | *Can sandblasting "increase" rust? Or, if the rust is removed and the metal is sealed, shouldn't it be eliminated? Some thoughts on this are: | ||

*POR-15 is largely considered a "duct tape fix" or a "git-er-done" solution. It may be OK for the home hobbyist, but it's not considered the "right way" or the "professional way" to handle rust. | *POR-15 is largely considered a "duct tape fix" or a "git-er-done" solution.

*Brands: POR-15, Zero Rust, Eastwood Rust Encapsulator. These are not rust "converters", they don't alter rust, etc. They are a coating intended to seal out air and moisture. | *Brands: POR-15, Zero Rust, Eastwood Rust Encapsulator.

*Another argument against rust "treatments" is that many of them require the surface to be lightly rusted first. "Inducing" rust seems wrong to people. | *Another argument against rust "treatments" is that many of them require the surface to be lightly rusted first. "Inducing" rust seems wrong to people. | ||

*Sand is not recommended for media blasting panels. It acts like little hammers, warping panels with by compressive forces (analagous to hail). Use softer media (list examples). | *Sand is not recommended for media blasting panels. It acts like little hammers, warping panels with by compressive forces (analagous to hail).

*One recommendation is: after sandblasting, remove some more of the surface metal by sanding with sandpaper. This is done to remove the salt, sand, moisture, etc. from the surface. | *One recommendation is: after sandblasting, remove some more of the surface metal by sanding with sandpaper.
