Boosty: I removed the evap canister and was trying to get at the fender bolts because I was going to try to pop that nasty dent out of there...and I was "dry-fitting" my cone air filter to see how well it fit in the hole where the evap canister goes.
Barry: For the Seafoam, I used a funnel and slowly poured it into my brake booster line...it seemed to be the best option, and worked out great. I read here that you were supposed to let the vacuum suck it through, but the line seemed a little big for the can, and I didn't want any incidents where I couldn't get the hose out on time or anything like that.
As for the headlight removal, once again, I was just clearing room to see where (if any) bolts were hidden for the fender. That actually had nothing to do with my clear corners as I may have hinted at in my post.
