How to properly remove and reapply clear coat?

Hi I have some decals under the clearcoat of my aluminum bike frame. I want to make it simple and just plain aluminum. The decals are only on part of the toptube so I was wondering what is the best way to remove them. Should I just wet sand the portion of the toptube and remove the decals then reapply clear coat? or do I have to remove all the clearcoat then reapply? If anyone has info to help me with this, it would be greatly appreciated. Thanks

There's a good chance that you will sand through the paint or damage it when removing the decals and then need a new paint job on the whole bike. Not a good project for someone with no experience with sanding and painting.

Any new clearcoat (lacquer, enamel or acrylic) that you can get in a spray can will not be as durable as the original. Only lacquer lends itself to blending over an existing clearcoat. It can later be wet sanded with 1000-2000 grit and buffed out.

There is a chemically hardened urethane sold in a spray can for about $20, but it's not for beginners, since it must be used quickly after the hardener is mixed in.

oh i see, well it is just the aluminum under the decals so I thought it would be a relatively quick fix of just sand, remove, and reapply :/

If the frame is really just clearcoated aluminum with no paint or anodize, it still either has a polished or brushed finish on the aluminum. Sanding off decals will mess that up too.
