[svandamme]

small question , while yours is cut up :

the hot air piping , is that steel? eg > is that stuff that can rust or is that some form of plastic/polyester tube?

trying to find out if i could use that to channel oil lines for a front mounted oil cooler , eg push em throug that tube

of course , if they're plastic, or PVC , then that wouldn't be such a good idea...

second question > if metal : how rusty were they ?
do i have to worry bout them beeing rusty on my car ( since i can't see that from the outside, and didn't work on those last winter...)
