Title: Jet-hot coating, anyone?
Post by: samc on June 17, 2008, 07:38:05 AM
I have a spare set of head pipes, slightly rusty but good overall. I'm thinking about getting them jet-hot coated in gloss black; anybody have any experience with this?

Sounds good!

My personal choice would be semi-gloss, but that is just me!

Hmmm,

I have absolutely no experience with that product/company, but sounds interesting..
If you go ahead and do it please report back on how they come out, longevity of finish, etc.
I am thinking it could spruce up the dull black painted pipes on all our LS bikes....

Or, we could even go for RED !!!!!

it's going to be about $190 plus shipping. I still have the shiny black mufflers, so I'm looking to duplicate the original look as much as possible; the gloss black is actually a satin finish. I tried flat black paint, looks like flat black paint.

I've seen the silver finish, it's elegant.

I'll report back.

jet-hot does a great job, the nice thing about them is they also coat the inside of the pipes.

some powder coats will do the same as long has they are the ceramic type of powder but most dont coat the inside.

great stuff, i have used it on a couple of custom exhaust that i have built, the cool thing is they also have a silver metallic that can be polished up to look chrome-like, it will fool you from 20+ feet away but closer you see it is not chrome.

I don't know why, but the gray appeals to me, for some reason.

got the pieces back today. They were badly pitted and rusted to the point where I was considering tossing them; they're still pitted, but much smoother and with a very nice semi-gloss black finish :D. I'll post pics when I get them installed. The biggest problem I see is that the mufflers are shinier than the pipes now. Hmmmmmm.

As far as pitting, the pipes I coated with the Eastwood Satin Black were very pitted.  I just used an oxy/acetyl torch and dropped some weld into the pits and filed/sanded them back down - kinda like Bondoing a dent.  After painting there was no sign...

If one were to have a large enough dent on the lower part of the curve of the header, (left side - I will have to take a picture)
could it affect performance by reducing volume on the one side?

IOW, I could replace them, as planned, or I could fill and paint.

Either way, I need new mufflers.  These are just real tired.

A large dent might disrupt exhaust flow but could easily be snatched out with one of the dent puller kits that weld on a little stud to use with the dent puller.  They work fantastic on gas tanks as well, I did sort of a demo at one of Ken's Rallies as he has the same kit as mine.

The motorcycle is worth (to me ;) ) a new set of headers!  It was just a passing thought.
I would think the thicker metal and the tight radius of the header would make the puller more challenging than on a tank.
But since I have never tried it...

It welds a steel stud to wherever you want and you grip the stud with a slide-hammer.  You'd be surprised, but I guess it's all academic if you don't have access to one...

I have a slide hammer.  I don't have a welder.

drop by; I do. glad to help a bud out. If that's too many time zones, I now have a spare set of head pipes (chrome and dirt color, with rust highlights. Very trendy).

Hey! I got mine from the same source as yours! The hot rod cars guys call it, Patina. Recently saw a high-dollar, checkbook-built rod with... wait for it ... FAKE RUST!  At least ours is authentic.

OOoh, aaaaah - they do like nice and shiny black !

What did you paint your wheels with - powder coat, or ??

Post by: Justin B. on July 14, 2008, 07:54:29 AM
Sam, that looks great!  Did they mask off where the pipes slide up into the head or is the coating "thin" enough to allow them to fully seat without clearance issues?
Title: Re: Jet-hot coating, anyone?
Post by: samc on July 14, 2008, 09:29:25 AM
the wheels are however they came from BMW, including the visible separation where the two castings meet. Those are some cheesy alloys.

The Jet-Hot is relatively thin, no clearance problems with the head. I did use a 1" sanding drum (actually, a flapper wheel) on the insides of the crossovers to get enough clearance for them to slide on (Jet-Hot coats the insides of the pipes, too). It's pretty stout stuff; minor bending of the crossovers at the ends, away from the slit, doesn't crack the coating. On the down side, the pits, etc are still there and probably worse than when they started, since they bead blast all the rust and stuff away. Of course, being satin black, they don't really show either.

That's a GREAT looking bike!!  I like the yellow and black together.  Nice look.   [smiley=thumbsup.gif]
