Agreed! I have a set routine whenever i get a new toy, be it car, bike, bicycle, RC etc. Replace as many fastners as I can with stainless steel, retap bad threads, and coppagrease aplenty!
I have a fixings shop within walking distance from home, and the guys there will happily find me odd stainless bits, plus I keep lots of metric allen heads, bolts, nuts etc ´in stock' ready for the next project
