Using the same technique you used to apply the primer apply 2 3 light coats of high heat spray to the exhaust pipe.
Painting aluminized steel exhaust.
I paint all my aluminized exhaust kits with rustoleum high temp bbq grill paint.
Then i just touch up any scratches from install.
I ordered a new set of chrome tip muffler deletes from remark.
Our engine block paint comes in dozens of universal colors as well as oem shades such as old ford blue hemi orange and buick red.
I do take the time to clean the exhaust and paint it prior install.
June 06 2018 01 00 59 pm here in sunny kalifornia is there any advantage to painting new aluminized exhaust pipes other than the ll look pretty for awhile.
Oem exhaust systems are typically aluminized steel and are way more common.
Follow the directions on the high heat spray s label to complete the curing process.
It has held up well over the years.
It s strange how that noise sounds eerily like a voice in my head ordering me to kill snookie.
A common problem with aluminized steel exhaust is rusting from the inside out.
I use the brush on stainless steel header paint from eastwood.
Then let the paint dry for 1 2 hours before moving on to the curing process.
Been very happy with this method.
If you thought the engine gets hot you should see the exhaust parts.
Either will rust aluminized is just a steel pipe with a coating on the outside.
Your exhaust behind the headers will not get as hot as the headers and the paint will hold up quite well.
That moisture causes the inside of the system to rust.
Moisture collects inside the exhaust when it s cold.
The hard part with exhaust painting is the expansion and contraction with the heat and cool makes the paint crack and flake.
Aluminized steel is not as aesthetically pleasing or as rust resistant as stainless steel.
The aluminized will take longer till you ll see rust but it will rust too.
To or not to paint aluminized exhaust on.
I m too poor for the expensive stuff.
In my basement you can hear water in the pipes.
We have 2k aerospray engine paint as well for paint gun free applications.
Headers are hardest on the paints.
It has a much more dull appearance than stainless steel does.
It has held up extremely well and has not chipped or flaked for me yet.
I d go with the aluminized and paint the welded areas as well as the seams bends and it ll look good for quite a while.
