Old Saw

Ttxela

Mac-Valve Maestro!
I recently picked up an old saw to paint, I've looked up quite a bit of advice on prep for painting saws but it's mostly based on coating the whole saw. I'd like to paint a design onto the blade and leave the rust and 'patina' showing.

What's the best way to prep the saw without cleaning it up too much?

I have a couple of saws from my father and was thinking of doing something similar. He used to cut all sorts of woods that were loaded with sap and would paste wax the flat part of the blades to prevent or reduce gumming it up. Clean off your saws with acetone or similar aggressive solvent cleaner/degreaser to strip off any wax or sap.
Have fun with your saw project. :thumbsup:
 
4030 could work, but it’s their new 4050 UVLS clear that they recommend for adhesion promoter. The Transparent Sealer would also be a choice. Like Mr M said the 2k and then sand would be another way to go.

I think I would give it good clean and degrease and then do the 2k clear option. Only because solvents make a chemical bond where water based is a mechanical bond and I think chemical is stronger. I'm interested in what yo do anyway and of course will watch your video which I know you will make.

Most water-based primers do a better job than a normal synthetic primer.
If you go to the epoxy primers with Etching properties then there is a chemical bond.
Normal 2k clear does not have those Etching properties.
So the UVLS is not that crazy .

But to seal the rust, the 2k is a better option

I would sand the entire area, Primer over the area I wanted to paint and patina the metal where I didn't.
and then 2k clear over the top.

It's December now, your neighbors should have their windows closed.
