If I read your post correctly, 200 amps ?

I don't think the COPPER will do the job.

or, you got one heck of a trace there.

As far as protecting the copper, spray laquor is to keep it from 
tarnishing.

if you want an all weather protector, be aware that the heat from a 
200 amp trace may burn off most everything unless you are using some 
pretty thick and wide traces.
