I remember reading (a long time ago) a diy on making your own charge pipes, and in the diy the car used some sort of rubberized coating over all of his pipes. I cannot for the life remember if it was some fancy sort of heat shrink or just something of the spray can variety.

I ask because I'm planning on fabbing up a new intake soon and would like to coat it with something so it's not bare metal.

If this is in the wrong forum please feel free to move

 

Most people just go with paint. As long as you clean it, scuff it up, use primer (or selfpriming metal paint), use fine coats, and let it dry in the house, you should be fine. A rubberized coating would only lightly protect it from scratches, as any rubbing against the body will cut through it in 100 miles.

All the rubberized coatings I've seen cost a lot as well.

 

the rubberized coating you can buy in spray cans at autozone or wherever and it works great ive used it on a few of my friends cars in the fender wells and it holds up great!

here is what i used..... the professional undercoat with sound eliminator
