Bolens was powder coating at this time which is probably why the paint acted differently than what your used to on the older stuff.
Are you going to clear coat when you are done? If your rattle canning the whole thing I would strongly suggest that.
I didn't know Bolens power coated their machinery. No wonder it was a pain to deal with.
The paint I am using is antique tractor paint, exactly what I use on my restorations. I've never clear coated, and it really isn't necessary in my book. The paint will fade if it is in the sun, certainly, but so will clear coatings over time. Clear coating also shows scratches something terrible, and if Dave wants to work this tractor, it will get those.
I'll let him decide if he wants it or not. I don't have a problem doing it, its just not on my required list.
My experience with older restorations and clear coating was not good. Maybe it was the painter, I don't know.
I would still use clear coat if I was restoring a museum piece that was never going to get dirty again.
I'd like to hear your thoughts, though. What is your reasoning?
