H-400 Posted February 16, 2020 Share Posted February 16, 2020 Hi everybody, did anyone used rustconverter on an exhaust pipe? The one bolted on the exhaust manifold so it gets hot. Grts, Herman Quote Link to comment Share on other sites More sharing options...
®evo03 Posted February 16, 2020 Share Posted February 16, 2020 Herman, have you ever heard of molasses? Try you tube. It takes about 2 to three weeks, less destructive than sandblasting. What are your thoughts to protect it afterwards? Ceramic coating? I like the three week waiting time, as it relaxes the time, allows me to put my feet up! Relax and wait, and not listening to a noisy grinder with wire wheel. All i needs is a truck of molasses, and a large manta size swimming pool!

H-400 Posted February 17, 2020 Author Share Posted February 17, 2020 Hi Evo, never heard about molasses so I checked it out on internet. Weird what you can do with sugar related sirop...The exhaust pipe is allready cleaned with yes the grinder and with Rustyco rust eater. Just wondering what will happen when I use rustconverter (that stuff that colours the bare metal into a bleu/black finish) on that exhaust pipe? Will it give fumes or will it peel of again? Maybe I'v got to try it on a piece of metal and heat it, or on the exhaust manifold of my Son's Corsa😁 Quote Link to comment Share on other sites More sharing options...
Jessopia74 Posted February 17, 2020 Share Posted February 17, 2020 If it’s not high temp stuff it just burns off and smells 1 Quote Link to comment Share on other sites More sharing options...

Molasses sugar syrup, eats into rust and removes it, it is gentle enough if the metal is in good condition to polish to a mirror finish, it leaves no residue, and final step would be to wire brush metal, and either prime, paint or protect, The rust coverter, cannot be left unprotected, metal will rust again. I suggest molasses, as it is natural, needs washed of with water, a tank is better to dip large parts. Then high temp paint, or better ceramic coating.

H-400 Posted February 19, 2020 Author Share Posted February 19, 2020 Thanks all for the help, will paint it with a rattle can of Hammerite heat resistant paint. Also the cast iron exhaust manifold. 1 Quote Link to comment Share on other sites More sharing options...
garymanc Posted February 20, 2020 Share Posted February 20, 2020 Stove enamel paint might be your best bet Quote Link to comment Share on other sites More sharing options...
