George's random questions/thoughts for the day, Rust in front trunk, repairing valences and exhaust Options

[ThePaintedMan]

More random thoughts from George... Does anyone have any good suggestions for cleaning out and repainting this hard to reach area? As far as I can tell I don't have any cancerous rust there, but since water has collected over the years, some areas are starting to rust on the surface. How would one go about stripping the paint underneath the headlights on the floor of the car here, since there is only that one coke-can sized hole? Then, how would you go about neutralizing it and repainting?

Also, I have a rusted, but still useable front valence which I'd like to try to repair. The problem is the metal is so thin, I'm trying to think about how I'm going to do it. Not looking for concours stuff, but more or less wondering if anyone has even done it before? Just keep the welding heat low and try not to burn through?

Another random thought for exhaust builders: is there any advantage to having a cross-over between the two banks? On American cars its usually called an x-pipe or h-pipe, and I've heard it helps with scavenging. Always wondered why we don't see more exhaust systems, other than those like Chris' from Tangerine that connect both banks together before it exits.

Thanks for your thoughts and for putting up with my randomness.
