Welcome Dante,
Remember sometimes subtle is the key to true customs. It's hard to continue to say you have a fine automobile when you have Naked women mud flaps hanging under it
For a beginner, tasteful wire wrapping is a good starting place. Now days you can find very good quality Triple chromed nuts and bolts SAE and Metric at a lot of your better Hardware stores. Remember if you don't throw Bling in there face and they need to look for it they look just a little bit longer. When people say KISS, keep it simple stupid it's to bad they can't ad CLEAN to the saying.
Mike
