Nick, you should make sure you get some sealant also on the gaps
where the paint hasnt reached and where water and dirt will over time.
Youve done so well so far it deserves it.

Looking like a beautiful color look forward to this one.
Back to the rims how about a cheap set of 15inch centerlines as
the have a clearance at the moment.
http://centerlinewheels.com/wheel_deals_list.phpYou can get the GN or the Stealth with the centre caps machined
with the datsun logos (get 4 allen hex dome bolts instead of 2 as well)
Paint the outer rims white (easy to cover the gutter rash with white paint
as you need to) and a thin inner step inside to paint mat black so the white
is contained in the black from the low profile tires (195/50/15 and the black
on the machined inner groove.
Youll have the wide alloy steelies and hub cap look with either plain hub cap
or retro hub look.
