Hello.. Could someone recommend the best way for me to paint this metal
railing by my front door ? I have a picture of it here -

As you can see the paint is already crumbling off from last year's
coating... Yes, I actually had it looking good last year.

I asked my dad and other friends...and most people seem to have the same
problem... Its so hard to keep a good coating of paint on these types of
railing.. Its such a pain in the butt to paint too. I used a brush last
year.

Any recommendations on types of paint and methods to use would be much
appreciated.

thanks much,

John
