Fiberglass fenders on the street?

I have fiberglass fenders, hood and bumpers on my Scamp. So far on the street and down the track they are looking good. The only thing I did not like was all the time I put into the fenders and hood to make them look nice.

That's actually my biggest concern - I figured there's not too much to it once they're on - it's just how much time and effort involved in mounting, getting the headlights set up, and getting ready to paint. Is it reasonable to think I can get a set prepped well enough to not know they are steel or fiberglass once painted?
