Hey everyone! I've got a large aluminum piece that's been powder coated, and I really need to strip that coat off without altering the original size of the part. Sandblasting is definitely not an option for me. I was thinking about soaking it in acetone overnight or even longer. My question is, will that effectively remove the powder coat without damaging the aluminum? If not, what other methods or alternatives do you recommend?

You could try calling some powder coating shops in your area instead. They often have access to stronger chemical strippers that can get the job done without damaging the aluminum. Commercial solutions work faster and are generally more effective. Just a heads up, you'll need to check their policies and pricing since they can vary quite a bit. Also, if you do end up going this route, they usually have procedures to minimize any risk of damage.
Definitely avoid just soaking in acetone. Your best bet is probably a quality powder stripper that’s specifically made for this. Although, just so you know, these chemicals can be pretty hazardous, so you’ll want to make sure you're equipped with proper protective gear. Don’t forget, it can be tough to buy without the appropriate business identification, as many suppliers require a W9. If you can, find a local service that can strip it for you—it’s sometimes the best solution without the hassle.
Unfortunately, acetone alone isn't going to do the trick for powder coating. From what I’ve seen, powdered coats are super resilient, especially on aluminum since you can't just burn it off safely. If you’re willing to consider alternatives, I’ve had success with methylene chloride, but it's really potent stuff and not the safest option. There are also paint strippers available today that can work, but heat combined with the stripper can really make a difference. Just make sure you're careful about the parts you choose to strip—I doubt it's a problem when it comes to tight tolerances, but it's worth considering if you're worried about the integrity of the piece.
That’s a good point! Make sure to use gloves and a mask when handling those chemicals. Safety first!
