Anybody know of some hi-temp epoxy or filler?

Got my exhaust manifold setup. The Heat shield is solid but pitted after being sand blasted. I would like to smooth it prior to paint. I was thinking maybe some exhaust repair putty. Let harden, sand smooth and then paint with hi-temp blue. I see they also make 1200 degree primer. I'm thinking I could also load up the pits with primer and sand smooth. Anybody know something that would work?

 

I would think maybe some brass brazing would work or some type of mild welding???

 

Or maybe some of the stuff they use to fix furnace cracks?

 

Possibly one of the hi-temp epoxies from Cotronics? I have a whole tube at home if you are interested. Can't remember which one I have off-hand. I'll have to check when I get home later.

I'll have to check what kind of goodies they have at Ace hardware ...

 

I don't believe you will find anything hi-temp for exhaust work at Ace...I checked but again I was looking for really hi-temp stuff. I used it to epoxy the port divider in my I6 head before installing the headers. The stuff I have from Cotronics is good to 2300 deg f.

 

Where did you buy the Cotronics stuff?

EDIT: Oh ... I just saw you said you have a tube ... I am interested if it's good enough to withstand the exhaust manifold temp .... Thanks!

 

Here's the link so you can read about it and decide if you think it will work. It comes in an 11 oz tube and cost me $18.50 plus $15.79 shipping and handling fee. I know...they socked it to me for shipping and handling since I didn't meet their minimum order amount. I'll let you have it for $20.00 delivered to your door. BTW, I probably barely used about 1 oz of the stuff, so the tube is pretty much full.

Does it seem like I should be able to spread it like filler? Does it get hard enough to sand smooth and paint? Thanks ...

 

Maybe I'll just leave them pitted ... Here are some pics of a restored engine going into a 429 CJ Mustang ... notice they left the pits and painted it up ...

 

Are you going to put the engine lift hooks on? I don't know about '71, but my '74 had them. I tossed them somewhere, not sure where.

I have had these laying around for years ... They supposedly came off a Maverick ... they look awfully long though ...



Ralph Prices car does have them ... but they appear to be shorter ... you can barely see it in this picture.

 

You could definately spread it like filler. Not sure about sanding it once it dries. I'll try it on an old exhaust manifold and see how it works. I'll let ya know.

 

Gene .. don't worry about it ... gonna just use it as is .. once on the engine you can't see the pitted area anyway ....

 

Funny, mine had rubber on one side and not the other like your pic. I always thought one was missing the rubber? I don't know where they ended up. Mine were long like your pic. I left them off when we rebuilt it in 1988.
