thermal coatings

so i was reading more on thermal coatings and came across flow coat coating". its a hydophobic,teflon type coatingto improve airflow and fuel residue and carbon . the coating cover the exhuast and intake ports of the cylender head and also the ends of the valve stems ...the thickness can be between 0.6 and to 0.30 ,0.35 ,0.45mm the gains can be from 1-2 % but it ruduces friction. imporves spool for turbos and lowers water and oil temps it may be somthing i want to gini pig for my head.

however i already have had my head port and polished so would i have to prot my head 0.35mm more for a 0.35 thermal coating ?also i haveto have my valve guids seals.ect replaces so would i have that done first?im goingto give them a call.

You could think about Polydyn as well.

http://www.polydyn.com/index.htm

Their website isn't great, but I had them do the inside & outside of the exhaust housing and rotor faces with a heat resistant coating, and the rotor sides with an oil shedding coating on my RX7. All have held up well (just had the engine apart again). That said, I had them do my header as well, but that part seems to flex too much and coating is flaking off.

they look pretty good but it doesn't look like they offer any heat shedding coatings like the BBE from swain tech. I really want to get my i/c covered in that stuff, it would be neat to see how much faster I could recover from heat soak with it. It also sounds like it would look pretty cool... as you can probably deduce Im a fan of sleepers and having a black intercooler would add to that effect.
