propeller weathering

I have been building models for some year and have noticed with other modelers aircraft that no matter how weathered they make there aircraft the props alway look like they brand new and it stricks me as odd because as a pilot my self i know from all the prop driven aircraft i ave flown the about 90% of all of them have alot of leading edge wether but dont dispair fortunatly it is a very easy problem to fix on already finish models first dry brush a light coat of flat silver on the leading edge only demending on how weathered you want it next u must dry brush black or what ever colour u made ur props  and now i think the plane would look more realistic an it does not take so long so try it out and let me know what u think and pics of your updated work would be nice so happy modeling
