that was done to our 1755--- looked  great  for  3 yrs--  right up till we  put the  1755 to work on the grain vac   and got  the muffler  hot...

that  muffler paint went to flaking...  and  it now looks like the muffler has the Mange.

I would say  you could get by  painting  IF you dont plan on working  the tractor  hard.    Also  the 1755 is Diesel and the exhaust temp  is hotter.
