Steel-It stainless steel spray paint
Back when EGT probes were a thing, and the tuning method with AFC was to find the lean setting before the EGT temps jump ( which is actually the lean setting before knock and timing is being pulled back ) I was wire bush stripping corrosion and rust from stock heat shields.
To stop the rust, I would prime the stripped metal with cold galvanizing spray, and then top coat with Stainless Steel spray paint.
I had no idea how well this would hold up - but now I do. Check out the old heat shields at the top if the image. These lasted. 10’s of years.
The middle shield is recently stripped primed and painted, and the lower shield is brand new factory part for comparison.
You can all thank Mike W at RRE for letting me experiment 20 years ago, and the luck to find a product that still exists today.
