Painting Pullies

[Bradley G]

Any advice on painting pullies?
I am trying to refinish a set of Steeda underdrive pullies.
These were on My Marauder, Bought used from a MM.net member, Given to Rider90 , sold to Marauder03, he used them and sold them back to me.:D
Hey wait a Minute, I payed twice!:P Oh well.

They can't wear out, Can they?
The waterpump pulley, seems ok,paint wise, But the dampener is cast, spray can paint, doesn't seem to stick well.I may have applied to thick of, a first coat.
I used to have the body shop, at the dealership, I work at, but new ownership dissolved the department.:mad:
Any suggestions? maybe just thinner coats?

Always go in thin coats for best adhesion.

Try to sand and prep them as best as possible.

Paint applied to the 'grooved'/drive portion of the pulley will probably be stripped right off after even limited engine use, more so with Gatorback or similar performance belts.

Also, make sure the damener is in good condition prior to install to prevent component failure.

sand or media blast, powdercoat. done never worry about it again.

Otherwise, sand paper, more sanding, and clean, then paint. I like Krylon, they seem to have extra strong fumes...that makes it better, right? :)

You could always try a base of epoxy primer before your color not sure how that would work on pulleys but for exterior its supposed to make anything stick to it. Also it seals out moisture so you dont have to worry about them rusting from the inside out.

Would heavy paint cause a balance issue???

I'd be impressed if you could get that much paint on it to cause an imbalnce issue.

Maybe something spinning at a couple of 10K rpm might be an issue

Sand it down good and get a can of Prep-All by Klean Strip. It removes oils and impurities from the surface. Also, most auto parts stores sell a paint adhesion promoter you can spray on before or after the primer, then apply the color paint of your choice.

I tried thin coats, light#320 sanding in between.
This Rustoleum paint, just stinks.
I can scrape it off with my fingernail.
Tanks, I'll get some prep and better paint, like Krylon.

If you put it on bare metal it will easily scrape off, especilly if the surface is to smooth. You need to roughen the surface with 100 grit, then a couple coats of primer wet sanding in between. Wipe it down with the prep-all then two or three thin coats of paint. It takes a little work to make it last.

You can doo it!!

I thought using 100# sand paper would take alot of time to sand those scratches.

I don't have a piece of the 100# to see the grit, but it was a suggested grit to achieve a purpose. You may be able to use the 320#, the thing is you have to dull the finish of the metal so its not so shiny. Then thats where the sandable primer comes in. Spray it lightly wet sanding between coats with finer grits, 800 to 1500# ( depending on brand of paper) till its smooth again the paint then adheres to the primer and won't scrape off with finger nail. Of course you will have to wet sand the paint between coats 1500 to 2000 grit to get it smooth. Then shoot it with clear. How many coats depends on how durable you want it. Remember the problems some black MM had, that was part of the problem, not properly preped and not enough paint applied. Rustoleum is good, especially for it's rust inhibiting properties.

Some others may chime in with their experiences or tips and anything i've missed.

Brad,
Clean well with laquer thinner. Lightly sand with 400 to show some metal. Use and ACID ETCHING primer and try to avoid getting any on the dampener rubber. Use light coats of your favorite paint. Clear lightly, then heavier.
Bake in an oven at 150 degrees for about 15 minutes.
Good luck. Take your time.

Thanks for the refinishing tips.
I have not heard of acid primer.
I got some industrial Rustoleum primer and paint, resists chipping.

The biggest issue you will experience with rattle can paint on such an object:

Discoloration.

Powdercoat resists staining and cleans up easily. It also handles heat well.

I'd powdercoat.

Mayby not even send them out, but try g3's caliper paint.

15k later and my calipers were as red as the day they were done.

Rattle can WON'T do that.;)

That's a darn good suggestion to.
