Rattle can paint job on rim, will it survive?

[m9hundo]

I have a marchesini 5 spoke front that is gray and I would like to paint it black.  Can I rattle can it then take it to clear coat and have a presentable durable paint job?

TIA,
Gil

Scuff it up everywhere, clean it off with contact cleaner, and paint it.

It may suffer a bit on tire changes, not so sure about that.

I did this 4 years ago, wheels were originally black, I just added the red.
They still look the same.

man those look sweet!

did you just rattle can over the black??

Thank you Nick, I'll have you change the tire so I can blame it on you when the paint chips, jk.  Did you clear coat them afterwards?

You can't usually clear on top of rattle can unless you use rattle can clear.

You can uerothane over a rattle can paint the same as you would with any other paint and it will have the durability of whatever the top coat it. Just make sure any primer or base paint adheres well.
As for durability, I haven't seen anything that stands up well to rock chips and careless tire changers (including powder coating). I try to use a paint that will be easy to touch up. Anything with a clear over it tends to leave a halo when touched up but Ducpainter might have so ideas to minimize it.
The ideal paint to touch up is flat black, anything, anywhere.

is that because the industrial type clear will eat away the rattle can paint?

[Speeddog]

Yes, I just rattle canned over the black.

No clear coat.

i think the rule is, you can use a urethane clear over laquer, but not enamel. or something like that.

i used a acryllic lauqer on my tank and then had a  urethane clear over it. looks great, but the clear was too soft for my liking though.

i think FISHEYES!

Most rattle cans are enamel.

Mot automotive clears are urethanes.

The enamel wrinkles.

...and he man is right....kinda.

You can use a urethane over lacquer but you need to use an adhesion promoter/inter coat clear to maintain adhesion.

What brand of paint did youse use?  Seems like there's a big variation in rattle can paint quality and price isn't always a good indicator of quality.   I remember a long time ago someone did a rattle can paint study/test to find out what brand is best, but it's been so long the results probably aren't valid, plus...I forgot who won.

I've done this probably 100 times. All you have to do is give the base rattle can about 2 hours to set up otherwise is will alligator. And, yes, there is a significant difference in the quality of rattle can brands, but I forget which is which.

Rust-Oleum, Sunrise Red.

Krylon is good stuff as well.

^ Yep, those are the two I use.  I *think* that I improve the paint durability of small parts by baking them at 250F or so for awhile but can't prove it.  But regardless of the results it's  very  fulfilling to sneak bike parts into the kitchen oven.
