I've also seen cars with what appeared to be seran-wrap(spelling?) or that stuff that looks like seran-wrap on packages that arrive in the mail, wrapped around the whole front end.

What is that stuff? Is it just seran-wrap or is it similar to "racer's tape?"

 

You might be able to get some at a local race shop. Let me know if you if you want some, if you cant find it. I think they also call it "helicopter" tape or something like that. If you're really worried and plan on doing future event, i'd say buy a bra.

 

Type Goch: Know of any shops in the L.A. area that might carry it?

 

You can buy it at the Buttonwillow gift shop if you go. It might be expensive there though.

In regards to places to go for time trial events:

Also the Alfa club does a lot of track events, but I don't have a URL for them.

 

There's a local race shop in my area who sells it for about 5 bucks a roll. Probably not enough to cover your entire bumper though.
