I have a muffler with a lot of surface rust. What is the best way to prep for spray and what spray paint is recommended? I have used the high temps at the local flaps and they always stayt to peel off after a while.

I really like ceramic coating muffler/exhaust systems. It's not as cheap as spray paint, but it actually works and lasts for years and years.
My local powder coater offers it in a semi shiny silver and black. The last time I had a Bursch system coated it cost around $200. Still looks new 2 years later. . . You get what you pay for. (IMG:style_emoticons/default/beerchug.gif) |

I have had good luck with the stuff from the auto parts store, you just need to prep it correctly and heat cycle it like the can said. I have used it on a 2 stroke bike and my bug muffler.

Here's where I think you get way more than you pay for:
1. Take it to a local sandblaster to clean everything up. 2. Use either "POR-15 Exhaust Manifold Grey" or "VHT 104 Grey Exhaust Paint" 3. Follow the instructions for curing. I've used both and they both have/had held up perfectly for over 5 years. The POR-15 product is more expensive. I've been using the VHT lately with excellent results. I can shoot some pics today as I'm getting ready to put the exhaust system on the GT project this week. |

Only problem with VHT is it sometimes will not like to be touched up. The paint will curl and alligator when resprayed later.
I have also used BBQ black with good results. It will take a respray without fuching up the old finish. |

I have used the Techline 'Titanium', a ceramic coating. Its good stuff, durable and a ceramic coating you can apply yourself or have a shop do it. Color looks factory stock.
