I purchased Valspar Tractor and Impliment Primer, Enamel Paint and Hardner for my combination unit and since I need to wait on a new arbor am considering painting my slab saw as well as I cleaned it up good and haven’t added the oil yet. Has anyone used this pain on the inside of a slab saw before?  I am definently going to paint the outside but was considering painting the inside as well. My inside is currently just plain steel and doesn’t look like it was ever painted unlike the exterior. Will I just scrape the paint off when cleaning up?  I am especially interested if you used this exact paint before.

I used metal paint for I’m Home Depot it’s still mostly on the inside. I don’t see why it wouldn’t work

It will work if you get the inside completely dry (absolutely no oil residue) and use a really good primer, although it really isnt necessary as the oil on the inside of the saw will keep anything from rusting.

+++ Tony.  The time spent on painting the inside far exceeds the benefit, and perhaps even the enjoyment of looking at something with renewed color (temporary).

Thanks guys. Just did the outside only. For those wondering, I used the valspar tractor and impliment primer and the black glass tractor and impliment enamel paint. Amazons has it but is priced high compared to other places. This drys extremely slow so if you need it within a few day do not use this paint. I have never seen paint dry this slow before but many reviews say that happens but dries very hard.  The smell is extremely strong compared to regular paints so get one of the 3m organic vapor cartriges that fit their masks(I use 7500 series) Also be aware that the hardner is extremely toxic and your only really supposed to use it with forced air closed respiration. So if you don’t have that you might just want to let the paint dry for a few day to save your health.  I cleaned it up and scraped the old paint and used acetone followed by a slightly damp rag to prepare it. Remember to use dust mask with the old paint as may contain lead. Prep work took 5-10 times as long as painting so if you have oil films keep that in mind. Looks like it will hold up very well but a ton of prep time went into achieve that. This does contain an anti rust for those wondering.

Follow up, this did not hold up as well as I was expecting.  Even after a year the paint is soft and can be scratched off with your nail.  This is nowhere near as hard as people make it out to be.  Maybe Truckbed liner would have been better.  I used the proper primer and used like 30 cans of acetone cleaning it flawlessly and painted it 2+ full coats on top of the matching primer.  For those considering, it is not worth the toxic smell of this insanely unhealthy paint for it not to hold up.

That is a common problem with two part paints.  The mix proportions are really critical.  I have heard of people spraying hardener on paint that did not harden, but I don't know if that worked.
