Geeze... I can't face repainting the whole cowl!!
I just did a test of the Rust-Oleum epoxy white spray and it looks like a good match with the original paint.
Now I'm just waiting for some decent weather to spray.
I realize the overlaping areas may not look great... but it's mostly under the nose and hopefully won't show too awful much.
If it's too bad, I'll have to do the whole thing...
Thanks for all the help along the way!
