So im deciding whether or not i want to paint or powder coat my frame. What are the biggest differences? I know that powder coat is stronger and tougher but what does it cost? How hard would it be to just strip and paint it in my garage? Any special paints?
any help is appreciated
thanks

What paint is on there now? If it's powder coat, you'll have to use something like aircraft stripper.

I'm not exactly sure on prices. I know it's usually a bit less than anodizing. Maybe $80 to powder coat a frame? The advantage to using standard paint is you can touch it up and have it match...unlike a powder coat which can't be touched up with powder.

Powder coat is paint. Think of it this way...paint you are thinking of in a can is just a pigment suspended in a liquid solution. Powder coat is utilizing only the pigment in pure powder form and making it stick through electrostatic charge.

Powdercoat is more resilient because it adheres to the aluminum better (One of the processes in powdercoating is a chemical bath which etches the surface of the aluminum). It still scratches though.

I'd say some chemical stripper either way. If you have a pro do it for around $100 they will deal with most of it (acid bath for the old paint, etching, clearcoat, etc).

In your garage I'd say give it the chemical stripper, then sand it lightly everywhere so the paint can stick. Use primer and a clearcoat as well. Should be a bunch cheaper and last a little while. As for touchups, you could touchup powdercoat and regular paint the same way. (On my black PC frame I use either sharpie or a black crayon because I don't have any black paint)

You could probably have it stripped on the cheap. Aircraft stripper is really easy to use at home just wear protective gear especially on your eyes. When youre done I suggest wiping it down with a little laquer thinner to clean up any residue should you choose to paint it.

As far as strippers go, gasket remover works amazing. I have found that a hot water pressure washer works well for removing the loosened paint. But for whatever stripper you use be prepaired tp get high. . . that sh!t is potent

I had my Imperial media-blasted and powdercoated for $75. My buddy got his frame painted (in the same town) for $125 and that didn't include stripping. From personal experience, don't waste your time chemically stripping the frame, its a hassle and the supplies almost cost as much as most places charge for stripping(if they charge at all).

alot of powdercoat places now are asking for bare frames if they are aluminum. It all depends on how lucky you get and who has what equipment. Of the 8 shops I called in the baltimore area 7 said they wanted bare aluminum if they were to do anything, the last one said that there was a guy down the street from him that would chem strip it for him. Powdercoat is actually softer than paint and therefore absorbs some of the energy of the media to get around this alot of places would just turn up the pressure like they do for steel, but in the case of a bike frame that has been proven to weaken the frame. Chemical stripping is the safe way to get around this.

its also hard to compromise the strength of an imperial though. My giant dh team was powdercoated and sand blasted to strip. Its now a kitchen ornament due to cracks. Looks good though.

That sucks, the place I take my stuff to chemically strips, bead blasts then powder coats.

Yeah makes sense since the chemically stripping would probably remove the majority of the material. A light media blast to touch up any tough spots probably is still common practice.
