As -PKH- said, unless you are going to put a wheel pant on the front wheel it's going to look a bit odd to have wheel pants on the mains and not on the nose wheel. </p>

If you do want to fill the indent in the existing wheel pants using a epoxy and microballons in it makes for a excellent high strength low weight filler. It's very easy to sand and it is very strong. If you don't have microballons you can substitute corn starch instead. It's not quite as good as the microballons but will get the job done. Using 30 minute epoxy mix up a batch of epoxy and the slowly add corn starch to it until the epoxy is the consistency of peanut butter. Then fill your indent with it. Once it's dried you can sand it smooth.</p>
