Clear will definitely help, but you'll need to let the silver cure for a couple weeks first. The solvents keep coming out for a while. You can 'bake' the parts to help speed the curing. In your neck of the woods, just put them in the car with the windows up and park outside for 2-3 days.
As far as clear - DONT use the typical rattle can clear. It will turn yellow, especially in the heat. It may take a year, but it will turn piss yellow eventually. Buy yourself a few cans of
'2k' clear by spraymax. I used the stuff to redo the bumper of my daily driver and it's held up for the past 7 years. I've also used it to clear the saddlebags on my motorcycle and the gas tank too. The nice thing about the 2k is that it's a hardened paint. It won't dissolve easily and it's slightly flexible without being tacky, but is hard wearing. Read the directions THOROUGHLY beforehand and USE A RESPIRATOR. A bandanna isn't going to save your lungs from this stuff.
