Even tho your going the line x route I'll write what I did for others to see
1. Sanded all handles and both mirrors
2. Used Adhesion Promoter (2 coats,let dry for 30 minutes)
3. Satin Black Kyrlon Fusion (3 coats, let dry for 1 hour)
4. Rust-Oleum Satin Clear Coat (2/3 coats, let dry for 30 minutes)
has held up great for 3 months so far Heat,Cold ect
My hood handles even have Duplicolor Bedliner on top if anyone is interested in that extra step, for a textured look for there mirror's and handles.
