My new bike is coming in later in the week, and don't want to scratch it up like what I have now. I have got some light scratches on the seat tube from resting the bike on benches and trees. In addition to that some on the top tube from getting through doors. Also some on the chainstay from locking it up. I try to be careful, but I got to ride the hell out of it too. I take good care of my stuff, but bikes seem unprotectable!!! Is there some sort of total invisible clear plastic shield for frames, like they make for electronics? I am really wondering how all the pics of bikes here seem to magically seem be in perfect condition?
