Rust forming on powder coated frame.

[Husk72]

Long time since my 72 CR125 Husky has seen proper daylight, til yesterday.
I haven't had time, or motivation, to do anything to any of the projects I own.
So rush of enthusiasm, open container, drag said bike outside, and frig, rust spots on powder coated frame, in quite a few places.
Now... what to do ?
Can I paint over with rattle can paint, after clearing rust away, or, does it need to be coated again ?
If it needs to be redone, (coated), I wont bother.
But, if I go down the road of just repainting the whole frame in acrylic, would all powder coating need to be removed, or prepping lightly, ie, and giving frame and rust a light sand down, a shot of primer, then top coat sufficient to stop any lifting of new paint ?
Any information appreciated.

racer or garage queen - if a racer why not spot repair the rust work until it later needs a complete job again?

Was going to race it. Didn't think of asking myself the intended use of bike.
Thanks for tip. Have my direction now.
Thanks Ross ? Vicki ?

This is why i hate powder coating. Strip it back to bare metal and paint it is what i would do.

as said before on here powder coating is for pool fences not bikes

matter of opinion - have had powder coated frames preciously and still do - with no issues....................as yet    For something already done that way and being a racer some repair work on the powdercoating with paint will get you through to next major with no significant issues

Powder coating depends on how good the person applying it is. A good bake to get rid of any moisture before the job is the best way to go. You need to "educate" your powder coat guy on this. Never had any issues with powder coat bike frames or parts &  guy who "knows his stuff" can even touch up  suspect areas as required.

Had many frames powder coated and never had a problem either, my guy's preheat the frames and use an etch primer first, then powder coat over that. Maybe they left it sit for too long after blasting, and had some surface rust form. But you will have no problems painting over the powder coat.

Use 2K paint instead of acrylic if  you decide to paint it.

I have an IT200 frame which was powder coated, and the rust started under stone chips and infiltrated under the powder coat.

Frame looked reasonable in most places until it was blasted.

Strip and paint.
