hot dip galvanised steel vs stainless steel

[turbokid]

hi.. i know stainless steel is the ultimate when it comes to fertilizer but would it be any addition if i sandblasted a fert spreader hopper, patched up any weak spots and the sent it to be hot dip galvanised or would it be a waste of time?

If it came back the same shape I'd be surprised. Hot dip galvanising could distort it. Not sure what fert does to galvanising specifically though.

Would come back bent and buckled all over, sheet metal doesnt dip well, galvafroid paint might be a better option

If spreader is rotting get rid.
buy a fresh one

edit- ours is 22 year old and hardly a spot of rust on it. the day it goes wrong it will be replaced.

Fertiliser will just eat the galvanising. Put a handful on a galv gate and look at the rust patch for the next ten years if you want to test it.

Be as rusty as an old horseshoe in no time.

Galvafroid paint is almost a waste of time, and certainly would be for sower
Coating with something like body-shoot, or some of the newer two pack alternatives would last better, but fertiliser might not flow too well.
