Dwight Romberger Posted September 14, 2012 Share Posted September 14, 2012 Hi All,Even though my old exhaust was usable, In a moment of madness, I bought new exhaust pipes and muffler. It is the common "aluminized" steel type. If I am going to paint it, now would be the time.What do you think?Dwight Link to comment Share on other sites More sharing options...
FLYER15015 Posted September 18, 2012 Share Posted September 18, 2012 Dwight,When I replaced my exhaust manifold on my '40 LTD, I painted it black with VHT paint. I have since wrapped the pipe from the heat riser area clear down past the steering sector and master cylinder to the muffler connection at the "X" frame hole. Then I repainted the wrap with VHT paint again, to stop any "fraying".My goal is to reduce the heat in the engine compartment, 'cause here in Colorado we have a lot of 6% grades that go for miles, and "vapor lock" is a way of life, especially with us having to burn corn-gas.It took 50' of 2" wrap to do the job, and I watched Youtube vidieos on how to do it first. I used several aircraft clamps to secure the wrap,and soaked it in water first.I am quite pleased with the results. Have yet to test it out on the open road.I did paint the rear of my exhaust system with black VHT paint, and the mufffler is a gold anodized unit that looks quite new.Just my $ .02Mike in Colorado Link to comment Share on other sites More sharing options...
jpage Posted September 18, 2012 Share Posted September 18, 2012 Dwight, Eventually all exhaust parts will rust unless they're stainless. I used to clean and paint my Model A exhaust each year with Krylon high heat silver and it stayed nice for 16 years. I also painted the exhaust manifold with it and it kept the rust away for a long time and looked good too! I have painted systems with Hirsch stainless coating which also looks good and seems to work fine although it can be a little harder to brush. Both of these paints need the heat of exhaust to cure. If you chose to use a black high heat paint,read the can's instructions. Some ,like Krylon, require an undercoat of high heat silver under the black. If not,it just flakes off. I always paint my exhausts on antique cars simply for protection during restoration and it does help in the long run as plain steel parts rust very quikly!

Dwight Romberger Posted September 18, 2012 Author Share Posted September 18, 2012 Thanks for the response guys. Mike, That was a lot of wrap!I have used Hirsch paint. It seems to be very high quality or at least I seem to get good results with my skill level.Thanks again,Dwight Link to comment Share on other sites More sharing options...
FLYER15015 Posted September 20, 2012 Share Posted September 20, 2012 Dwight,Yes it was, and the stuff costs about a buck a foot. Using 2" wrap and overlapping by 1" it costs about 6 1/4" to advance 1" on the pipe. C = 3.141xD. If you remember the old Jaguar straight 6's their exhaust manifolds were black porcelain coated and it only lasted a few years before it started to chip off up near the cylinder head.Best Regards,Mike in Colorado Link to comment Share on other sites More sharing options...
Dwight Romberger Posted September 20, 2012 Author Share Posted September 20, 2012 Mike,I always liked the XJ6's. But all I remember about the engines is the big puddle of oil under them!I used the muffler wrap to seal the heat tube on my '30. I was expensive.Dwight Link to comment Share on other sites More sharing options...
