Re: How to fix scratch on frame?
The black finish on my 954 frame is kind of textured and flat colored. The only paint I can think of that ---might--- be close is a high temp engine paint that gives a more or less 'crackled' finish if you cure it with heat.
See if you can pick up a small spray can of that at an auto parts store, get a scrap piece of aluminum *( a beer can sounds about right.) scuff the finish and test it with various amounts of heat. Do Not 'test' it on your bike....
You may find that with some sanding, you can get it close. ( but I don't think so.....)
If it doesn't work, use a fine flat black paint stick and just hit the parts that show through,
or spend the winter polishing the frame,
or get yourself a Fireblades.org sticker, and slap that baby right over it !
