Alan is correct. That's the reason many times is better to save your pennies and send your parts to be coated by a professional.
Surface preparation is essential and you need to know how to prepare the specific surface. As an example, you cannot prep a Titanium valve the same way you do a Stainless Steel valve.
You also need to select the proper coating and curing process. There are specific materials, especially pistons, that its properties will be affected if you do not use the appropriate temperature and curing process.
My preferred companies are Swain, Calico and Polydyn.
