I'm not sure if the above is in reference to my remark about doing the 
inside of the masts and legs with the primer, but yes that is the primer to 
which I was refering.

"I think" there is a chemical reaction with the rust from reading the lable 
on the can, but I'd not gurantee  it.

If there's no rust I'd think that would be plenty sufficient.

It all depends on how messy you are willing to get. <:-))
Some just stick a high pressure spray gun into the end of each leg (with the 
section horizontal of pointeld slightly down hill). I cap off the ends of 
the legs using plastic pipe caps and wrap electrical tape around the outside 
over the bolt holes. Then I stand the section on end and pour in enough 
thinned primer to fill each leg.

Do this in an area where spilled paint will not be a problem. If one of 
those caps come soff , or the tape leaks it'll make a big mess in a hurry.
