more on fix'n wheels

[nwloves]

I'd like to thank all of you for the help in fixing some alloy wheels.
My next step was to create new center caps, which I did but was wondering
what I should coat these things with.
I used a lenses which I painted black and applied a vinyl audi insignia in
silver which I now have to protect from the elements,
Clear coat or?
Improvise! isn't the backbone of the audi owner?
TIA and I hope this doesn't fall into the "p o'd" about he same old
questions
