Anyone ever use swain coatings for ceramic coatings? Also I've read a lot that exhaust wrap has negative effects after prolonged use. Does that go for ceramic coatings also? Thanks.

 

twokrx7 has used them on his previous rotory engines and now on his LS1 implant.
He is an engineer and says their's is one of the best coatings.

Thermo wrap is only bad on uncoated no-stainless steel where it accelerates oxidation.

 

Funny you should ask, cause just yesterday i was asking the Swain reps are PRI about a problem I had with one of their coatings. Specifically I was asking why the White Lightning coating on my old exhaust manifold had "melted off," forming "Stalactites" on the bottom of the manifold. I considered this a material failure. Their reply was that it was not a material failure and "just the coating forming new ceramic crystals." Of course, the crystals had to come from somewhere, unless through some alchemy I'm ignorant of, it pulled the carbon from the air itself. If it did come from the coat layering, their must have been some unintention shifting of material. Anyway, draw your own conclusion. As for me, I'l never purchase from Swain again.

BTW, I've tried FOUR different coating on our turbo manifolds and have yet to find one that does not ether melt or flake off. We're just cursed with those hellishly high exhaust temps which are a significant challenge to the material performance of coatings.

 

Aparrently water hitting the hot maniflold(cycling) will also cause it to flake but that may be something related to the quaility and consistency of the product/prep/application methods. Read of other people complaining about that, although not being a direct user it may be just more internet bullsh*t that I'm passing along.

 

i did it in 1999, coated rotor faces , coated exhaust mani,, coeted turbine housing.

all good ,SWAIN tech the best.

one prob that showed up was heat was kept from dissapating into oil squiters, inside rotors, not good,, lots of power,, lots of detonation,BOOM BOOM, .

so i dont recomend coating rotor faces, if anythin increase oil flow to inside rotor, and good big coolers.

all else is good.

iv had it on my piston cars for 10 yrs no probs.

 

Good to know guys. Thanks for the input. I think im gonna give them a try on my manifold, turbine and downpipe.

 

They wont touch the inside of any turbo part, or part that could send exhaust into a turbo. They will only coat the outside.

 

While I dont have alot of miles on it yet I am having good luck with the Cilgen Satin Black from Techline Coatings. So far the coating has held up to a couple different 5-10 mile cruises on the highway in 3rd gear which was netting egts from 1950-2005.
