I do have krud kutter left but its not good for penetration. When I did the first test, I made sure I sprayed a little extra on the screws. They didn't budge. I'm also fairly busy with school so I'm not doing as much work as I'd like to with this machine. Basically, I only do work with this machine on weekends. Also I'm not sure on how much more work I want to do with this machine for now. Basically for this year I'm probably gonna unseize the machine, clean up the non-painted parts and wait until spring next year to paint the machine. Usually it snows closer to halloween or even later where I live. This year we got snow on the last day of summer and the weather has been miserable since. Spray painting in the house isn't an option either so I'll have to wait.
