Scrub it with lacquer thinner, then apply a good metal primer.
Yes, we generally consider stainless steel to be a nonporous surface.
paint it
no there metal
If it's true stainless steel and not a coating, then yes, you can paint a pool ladder with an oil based enamel paint.
The best way to get paint to adhere to stainless steel is to use an etching epoxy primer specifically made for stainless applications. Latex paint and oil-based paint are most commonly used.
Yes it does.
Oversimplifying it alot: Iron + Carbon --> High Carbon Steel High Carbon Steel + Chromium & other surface alloy metals --> Stainless Steel Basically Stainless Steel is ordinary Steel with a surface Chrome Steel layer protecting it from corrosion.
It's hard to get a paint to stick to stainless. Use an etching primer and then an enamel-type of paint.
The most common types of rods used for welding stainless steel are 308, 309, and 316. 308 rods are best for welding 304 stainless steel, while 309 rods are recommended for welding 309 stainless steel. 316 rods are suitable for welding 316 stainless steel and are also good for general-purpose welding of higher-grade stainless steels.
stainless steel has chromium added to the steel, which forms a protective oxide layer at the surface, preventing corrosion (rust).

No, stainless steel is pretty tough but if you paint a lot you should use a plastic basin to clean supplies.
