JohnRR,

We use the coatings all the time in our shop.
Check out Techline Coatings.
They are very simple to use, and they do work!
We spray all our parts at the shop, and then I bring them home to bake them in the oven. The thermal barrier coatings, and anti-friction coatings DO NOT smell when you are baking them, so you don't have to worry about the wife complaining too much. We do the spraying at work, because that is where all the smell is, and we have a small spray booth there.
Try it, you won't be disappointed!
