PG Manifold-READ THIS IF YOU PLAN TO CERAMIC COAT

[Speedy3]

READ THIS IF YOU WANT TO CERAMIC COAT YOUR MANI. I'M SERIOUS. If you coat the mani right from the manufacturer, the coating WILL flake at the welds. There is oil in the welds from the welding process. Install it and drive it for a few days first before you have it coated. I guess you could also heat it up real good (Evenly) with a torch a few times. Get it real hot, but very evenly.

Mine flaked at the welds because of the welding lubricant used in the manufacturing process. Performance Coatings is going to re-do the coating free of charge, even though it's not their fault. Great company!!!!

By the way, mine is ceramic coated and i can touch it about 5 min after I turn off the car. The hottest I have measured it so far is 720 degrees at the turbo flange and 620 degrees on the tops of the runners. No glow-in-the-dark on my mani!

GET IT COATED!! It makes a world of difference!

when they coated it they should have baked it first, without the coating on there so all oils would seep out.

Then applie the coating and let it bake on via the oven or by just running it.

shouldnt it have been sandblasted too? mine was when i ceramic coated it

The company ceramic coating the manifold will always sand-blast the manifold before coating it. It's standard practice. The problem is with the impregneted oils in the welds. They don't do a hot heat cylcle and chemical wash as standard practice before coating it.

Make sure to heat it up real good, preferably on the car, before getting it coated.

The problem is that it takes a lot of heat to get out all the impurities. The baking process for ceramic coatings only goes up to 500-550 degrees F. It takes much more heat to get all the impurities out of the metal. I guess the coatings companies just do their job, coat a piece for the customer. It's not really their job to make sure that the manufacturing of the part left behind some impurities.

This sounds like a horrible coating job. I would expect a refund.

Then I would sent it to Swain tech. They are #1 in coatings hands down.

Sounds like a pita to install it then have to uninstall it again only to have to install it one more time after the coating..They should bake it..

Wow that's good to hear, I don't have a 3 but on my protege I have the old Spool manifold and I've gotten it so hot you can see the manifold glowing in the day. Yeah that was a hard run...

just recived one looking to ceramic coat if i can find a place close by to do it.

Ask them if they can bake it first.

I just want to know why the welds have oil in them? If the parts are properly cleaned prior to welding there shouldn't be a problem.

Not sure. Maybe its impregnated in the metal on just on the surface?

probably a protective spray after assymbly to prevent rust while sitting on the shelf.
