Cool, all that matters is if your happy with it, I'd keep the cowl cleaned out and run a hose in there once in a while and it should keep the problems at bay. Maybe squirt some zero rust as deep as you can in the fender outlets towards engine after you clean and dry it. This is a nice tight area that likes to rust too. Steel is ok with the brush of water, but as soon as it stagnates with leaves on top of it watch out!
Nice work, good luck!
