if you scuff it with wet sand paper the paint will get DULL... after that u have to use polisher compound. If the paint is too thin u have to be careful with the sanding.

Like for example meguiars hand polish #81 or a 3m one that is called almost the same way

THe meguiars product is pretty good but read the instructions, If you don't want to sand probably u will need to use the meguiars clay 1st then the polisher

Good luck.

Unless you're working with a two or three coat base I'd not bother with wet sanding even with the super fine grit you'd want to be using for this application. There's just too much risk of cutting through to the primer or metal. It's better to spend the time you'd use sanding on creating a dust free area with no air currents floating through and apply the last coat in that area and allow to dry to the touch before moving the frame. Likely there will still be a small number of dust spots on the paint but it won't be enough to notice and you'll have the final coat gloss. Then after it has dried for about a month so the final solvents are all gassed out and the paint is just about as hard as it's ever going to be "wax" the frame with a good autobody wax that claims that it de-oxidizes or removes swirls or cleans and rejuviates dull finishes. What you'll get is a wax product that also contains a very fine and mild abrasive. It'll go on milky, dry to a cloudy appearance and then you buff off the residue. Typically you'll notice a little bit of the color on the rag or sponge used to apply the wax aggresively and maybe a little on the rags. The finish should look pretty good and the abrasive action of the wax will polish off or at least cut down and smoothen any dust specks in the finish.

For someone working at home instead of a commercial type clean air paint booth this is about as obsessive as it's worth getting and a lot less work than wet sanding and working up through all the buffing compounds, clay and finally polishing wax.

Besides, if you're not using an excellent quality paint that is known for accepting a high gloss final polish then the very best shine you'll get will be the gloss of the undisturbed paint. With a soft paint, which is what many rattle cans are, all the rest of that stuff will not be able to give you a mirror like deep gloss regardless if the paint film won't support that sort of gloss.
