It's GO TIME!!!!.....BABY!!!!!!

Is paint that heavy?

You'd be suprised. I stripped the paint off my dragster frame and used gun blueing on it instead, and saved 9 lbs.

A litre of water = 1 kilo in metric.  It figures that to not paint a car would make it lighter.  I'd also imagine paint is a lot denser than water depending on what type of paint it was.

You reduce air resistance by painting it, plus you also protect the car from corrosion etc.

I wouldn't have thought smooth carbon fibre would have much more air resistance than a painted surface... and I wouldn't think corrosion of carbon fibre would be much of a problem given that its non-metallic.

i apprechiate yer ethusiasm for races scrap but for some reason i'd rather watch paint dry than car races

Oh, it corrodes, but not like metal.  I believe carbon fiber is quite stable.

It can react with aluminium, though.

thanks for the re-direct scrap

Q: On your web site you have indicated that aluminum and carbon fibre react so as to cause cathodic corrosion. Is this also the case with steel or cromoly steel and carbon fibre?

A: Yes, it is a problem with steels as well as with aluminum alloys. The easy solution is to prevent contact. One way to do this is to include a single light ply of fiberglass in the layup as an electrical insulator between the metal and carbon. Trek did this with their bonded aluminum lug carbon tube bikes. Specialized did too, and Kestrel uses small patches of fiberglass in the fork and frame where metal parts attach. Aerospace structures do the same. See NASA's document TM-584C, CORROSION CONTROL AND TREATMENT MANUAL.

Thanks, but I get it.

Maybe it is a colloquialism, but here, we say "Ya think?" to someone who has stated the obvious.

Lol, over here its taken at face value.

Not always- I've heard plenty of people use it in the context that dirtdawg did- but I suppose its harder to tell without the incredulous tone of voice.

It must be the snooty area I live in...
