If you think there is a problem with the paint on the First Choice tiller, check out a King Kutter tiller at Tractor Supply. One of the yellow ones.
I looked at one yesterday, and the paint jobs on the tillers was awful! It was bubbled, blistered, had runs, and in many places you could see the metal right through the paint. Bare spots with rust on top of that. Looked like someone used a can of spray paint and globbed too much on there at a time.
Otherwise the tiller looked heavy enough, but the paint job was certainly a bad indicator of quality.
I have Rhino implements that stay in the weather all the time and the paint on them is great. The only rust showing up at all is where the paint was knocked off by contact with something. The rest looks like it would really shine if I gave it a wax job. They are 4 years old.
