I’m cleaning my frame to get ready for paint. I pressure washed and went over it with wire brushes and wire wheels. I want to roll and sponge brush it on. I’m planning on using rust oleum or tractor supply brand paint for rust. My questions are: 1 Should I use a thinner? 2 Should I use a hardener? 3 Can I just use iso 70 alcohol for final wipe down before painting? I’m gonna give it one more power wash to knock the remaining dust off as soon as I decide what paint supplies I need. I did remove the exhaust from the muffler back. I want to paint it as well. I know it requires a different paint. Any suggestions on high temp paint welcome. Thanks!
