spray paint on mild steel?
would it be possible to use some high temp spray paint on the mild steel i plan on using for my exhaust and charge pipes? i was looking for aluminized steel but couldn't find any suppliers with straight up prices so decided to get some mild from summit. I know that it has to be covered or it will oxydize and that most people powder coat, but could the high temp be a cheaper alternative?

and yeah i saw what Ben posted, but he was talking about looks on aluminum, so only the outside would be required, where i need all of it painted

My intercooler pipes are mild steel. I painted them black with 1500 degree paint. No issues so far.

I bought 8 feet of 2.0" mild steel for $15... and no shipping charges!!!
The guy told me if I gave him a list of the bends I need he'd only charge me $15-20... I have a feeling my charge-piping/downpipe/exhaust is gonna be pretty cheap as long as I do the welding

I used Duplicolor "High Heat, with ceramic" DH 1606 (here: http://www.duplicolor.com/products/engine.html) in a few places- the couple of intake pipes I had to use steel for, and the lower half of my downpipe. (The upper half is properly ceramic coated).
The paint has held up very well on the intake pipes, but it is flaking noticeably on the lower downpipe section. I'd imagine that on a manifold or upper downpipe section it would not work at all.
On the other hand, the ceramic coating on the upper downpipe section is still looking good. I had it done in an aluminum finish and while it's taken on a bit of a patina, it's not chipping or flaking at all. Even the inside is still beautiful.

2 things, Do not paint the inside of your IC piping, and no paint is going to be able to live inside the manifold or DP.
Ceramic caoting is what you want there, also most places will not caot preturbo incase something flakes off in a big ole chunk and causes problems that being said my stuff is ceramiced on the exterior and it is the best 100$ i ever spent aside from buying the stuff in the first place, i easily cut my temps in half. A simple engine enamel or similiar paint does a excelent job on the out side of IC piping etc. I would not worry about rusting through on the inside that would likely take a very long time even with WI my aluminized steel crossover has no rust in it what so ever after 2 yrs and damn near 60-70+ gallons of WI mix pumped onto it.. You should be fine. GL man

i'm gonna pie cut it and show all of you my fugly welds. Magna you said that your pipes haven't rusted from the inside yet with your aluminized steel, would mild be that much different?
