So i just purchased a exhaust for my 135i. Unfortunately the muffler is chrome plated. I'd like to go for more of a sleeper look by making it flat black. What's the process to go about doing this the cheapest way that would last the longest.

I read up on it a little bit, and found that it's best to sand the chrome, apply some sort of primer, then spray paint using high temp flat black spray paint.

Can anyone that's done this let me know what products they've used? and the results?

just rough it up and hit it with some hightemp paint. no need to go for a show room paint job

 

I haven't done it but I've seen some exhausts painted with DEI High-Temp Silicone Coating(High Temp Paint). Just use a Scothbrite pad to roughen the surface and apply a couple of light coats. http://www.hrpworld.com/index.cfm?fo...action=product

 

I painted my entire exhaust using Krylon flat black BBQ paint.


First I used some 200 grit sandpaper to rough up the surface. Then I applied several light coats of paint until the entire exhaust was painted. It took about 2 cans of paint to get the job done.

My exhaust still looks great after almost 2 years.

 

I used high temp flat black on my cobb muffler, its been almost 2 years. Looks great

 

i just used a scotchbrite pad and used regular flat black, still looks perfect

wtf. lol.



anyways.... back on topic. i just sprayed with high temp black paint. i didnt bother sanding (i guess i should've.. but i dindt know better back then) its been 3 years and still looks great.

 

I'll paint your exhaust for a 12 pack.

 

yeah i know!!

 

haven't done it yet but have sandpaper and hight temp paint. doesn't seem too hard

 

i did it to my greddy evo 2 just sand it down then spray it with some high temp paint

 

i think krylon bbq paint is a good idea for its heat resistance, but in terms of cooperation, i prefer the rust-o-leum "professional" primer. its the one that comes in a plain aluminum can, and is a few ounces bigger than the others. It seems like this stuff will bond with any surface, and you would have to TRY to get it to run or go on anyway but perfectly smoothly

 

sand, primer, anykind of high temp
