Hello!
I have to break my I.H. U-240 to fix a clutch issue here in a day or two. In a weeks time I plan to have the chassis primed. The chassis has a coat of Ospho brush applied. How much of the chalky residue needs to be removed? Most of it comes off with little effort with a wire brush, how picky do I need to be here? Next, I plan to use PPG or Dupont epoxy primer on both the chassis and the sheetmetal. Some of the sheetmetal was etch primed several years ago and there is some light rust shining thru...I had considered using the Ospho on the sheetmetal but read that it leaves the surface of the tin a little rough. Is the Ospho worth the effort on the tin or just stick with the etch primer?
I'm not building a show tractor but something close to it...I want it as nice as it can be.Thanks for the advice...
