I have five sets of aluminum sliding glass doors, each 6' wide that opens
into an interior courtyard. They are all bronze in color.

I am wondering if it's possible to paint them white?

If not, is it economical to order all new metal parts in white (basically
replace everything except the glass) or it's not worth it as the labor cost
to take apart reassemble is prohibitive and may be more than just replacing
the entire door?

Thanks in advance,

MC
