Cleaned up how? You can polish the lugs, sure. You mean the oozy glue? I guess you could sand or carefully Dremel the glue overflow, but that's not unusual on Vitus frames... Some signs of oxidization will still be visible, when you're done polishing, unless you take off a heck of a lot of metal. But it will probably look pretty good with just a reasonable amount of effort.

Maiden 5 miles and a quick wipe down. Feels a tad small at 54cm. But much better than the 60cm They feel like they ride big. Bottom bracket seems high up.
Tall tires?
