I have read several posts elsewhere regarding the need to paint or stain the frame to prevent warping of the frame. Is this a real issue or is this just preventative overkill? Just curious I have had a 10" makerfarm in the box for about 5 months now waiting to find some good weather to paint the frame. The weather and my time off havent gotten on the same page yet. Now it is cold and I dont have a good place to paint the frame that would be indoors. So I am wondering if painting the frame would even matter. I am eager to start putting this thing together but want to do it right the first time. The machine would spend its time indoors in the luxury of an HVAC so I dont think that humidity fluctuations would be a real issue.

If I do decide to paint it would a simple few coats of clear rattle can rustoleum work or does it have to be a stain/sealer?

Thanks for any help.
eager to get started
