Re: Exhaust coating from Eastwood
Quote:
Stuff was Black. Only color available then. Reasonably priced, but I had to buy a second halfpint can. I shot my Heddmans inside and out. I thought with that and my arid Arizona climate, they'd last forever. I had never tried mummy wrap before, and didn't read the fine print on my Heddman warranty. Hedders were sandblasted, then shot with brake cleaner, dried and shot with the black goop. After they were only a bit tacky, I put them both in Mom's old Hotpoint range and baked at 500*F for at least 2 hours. Paint from the upper dripped onto the lower bank. I figured that was just a cosmetic blem. [I don't think that's where the rot started. ] After putting the DEI wrap on, I did not coat the wrap with anything. I put a Mr. Goodwrench crate 350 in my '71 GMC Jimmy in 1999. The OEM ramshorn manifolds that were on the PO's SBC were mismatched. One had 4 ports -- capped off -- for A.I.R. and the other was pre-emissions. I elected for the Heddmans, as repop ramshorns were rediculously priced. Hedders were 7 - 8 years old when I coated and wrapped them. Then they lasted 7 years more. I am no longer a fan of Mummy Wrap. ![]()

Re: Exhaust coating from Eastwood
I had the Rams Head Manifolds for my new engine done by Top Gun Coatings in Calgary and they guaranteed them for life. I've only put on 13/1400 miles on the engine so far but are holding up well. They also did my Edelbrock 2101 and guaranteed it as well. https://www.topguncoatings.com

Re: Exhaust coating from Eastwood
I never heard of it before here today. I spray professionally powder and ceramic coatings. I use ceramic coating made for exhaust and have never had a failure. Hope I didnt just jinks myself. lol That stuff is kinda high in price as well with the claims. It runs $79.99 for a 1/4 of a pint (4oz). I buy ceramic coatings made for exhaust for $70.00 a pint (16oz). As for the heat reduction I am not sure with this chemical but the ceramics I use do reduce heat. Thats why bikers love it on their exhaust.
