i take it its a black one.
to be honest its up to personal preference.
gold looks the nuts on the black escorts, but also does white,alan put a white set on his if you remember.
ive got silver on mine but its a safe plain option lol!!!! i might change them to gold when i get round to it...

as for the glue i would watch what u use for the wheels as sometimes the gel doesn't always hold the wheels in place in the long run.(weight of the model)
