General Rust Treatment Options

[ChrisPaegelow]

Hey guys, this is a general question about taking care of rust.
This isn't a 914 now, but my motorcycle, an '85 Honda Interceptor 500.
But rust is rust I guess! (IMG:style_emoticons/default/chairfall.gif)

Anyway, this is about the only rust on the thing, so it's really the first rust I've ever had to deal with (and it certainly won't be the last (IMG:style_emoticons/default/w00t.gif) )

So I want to make sure I do everything right!

Here's a picture of the rusty stuff:

And a close up:

So, I want to treat the rust on the center stand there, and on that other thing, which my shop manual calls the 'common collector.' I dunno what else to call it, the exhaust pipes from the engine go in one side and the mufflers come out the other side. Pretty simple. Whatever (IMG:style_emoticons/default/yawn.gif)

So anyhow, I can get both pieces off pretty easily, but from there I don't really know what I'm doing.

My dad has a little sandblaster that I can use, and plenty of that POR-15 stuff to spray on the rust.

Then I'm assuming I'll need primer and paint. I'm thinking I'll paint both parts glossy black, like the tailpipes you can see there, since that's what they originally were. Any recommendations on specific brands, types, etc? (IMG:style_emoticons/default/confused24.gif)

I think, while I'm at it, I might just repaint the mufflers too, because they're kinda scuffed up. Would I have to remove the paint that's already on them first, or what?

Guys, please just assume I have no idea what I'm talking about, cause I'm pretty new to this stuff!

But hey, I'll figure it out (IMG:style_emoticons/default/flag.gif)

I know for you guys this is little kiddies play, I just want to make sure I'm doing everything correctly!

So any bits of help would be appreciated!!! (IMG:style_emoticons/default/pray.gif)

Thanks,
Chris

Ok anyway, what do I have to do to the parts before they can be coated? I can sand blast the rust off, but do I use POR-15 on it , or no?

If you are going the POR route check the manufactures instructions. Basicly:
Clean thoroughly and remove all loose paint and scale.
Degrease
Use metal prep to stabilize any rust and to etch bare metal
paint with por 15
Since this stuff is exposed to sunlight you then would have to apply a top coat.

por is not designed for exhaust components - it won't stand up to the heat. They have a separate high temp paint. I don't know if even that will hold up to exhaust temperatures.

The por regime is not cheap and por15 itself does not keep well. Normally you write off a can once you are done (I've had some luck with using plastic food wrap and keeping it cool)

Put all that together and having someone powder coat it for you starts sounding like the cheapest way to go.
