Wet Sanding Clear Coat: DA vs Hand Sanding?

I would like to know what most guys do... Hand or DA?

Also, I don't have a DA sander right now. I had a Lowes one when I started the project but I wasn't very happy with it and returned it. I am willing to get a Dynabrade or an equivalent quality brand. I am totally ignorant in this area also.

So if you like to DA wet sand clear coat can you tell me what DA model, size pad, orbit (ex. 3/32) and the thickness of pad used for wet that you recommend or use. Also, if you don't mind, what brand and type of sanding paper you use for the DA.

I simply just want to be able to go the store or online and order the sander and all the paper for the project so I can get to learning and not spend hours and hours shopping just to be disappointed again or trying to save $20.

I hope you understand. Also, PM's are welcomed.

Thanks,

SAM

Sam....do yourself a big favor and save your money, but good wet paper and do it all by hand. When you use a machine, you have the chance you may burn through the clear, especially on the peaks of the body. Most all body shops I know even sand the clear by hand. I use a spray bottle with a squeegee. Sand and wipe the water away with the squeegee, that will show you exactly how your sanding is going. The clear will be all dull, that's the look you're going for.

Are you trying to get rid of orange peel or polish what you have? I like doing things by hand but a good DA can be very helpful depending on what you are doing. The grit you use is also very important....

Color sand 2 cents

I would do it by hand. You must be very careful even when you color sand by hand or else you will go thru on edges and curves. 3M paper is expensive but it is good. I sometimes buy cheap paper ...some is fair and some is pretty bad...delima.
Use different grits if you need to cut thru deep orage peel but be very careful.

I can't say I have orange peel but I must have it at least some places. I am just trying to make what I have look the best I can. It was my first paint job and I know there is a little trash in it, but I think it turned out pretty good. I will know more when I hit it later with some 1500 wet to really get a good idea of how good or bad it really is.

I have just seen people using the DA on color sanding and since I don't have a DA I thought I would ask what one is good or which one most people use.

I hope this helps, and if anyone has a recommendation on the DA such as brand name, throw (ie 3/32) and pad thickness such as 3/8 vs 5/8 inch. That would be great. I will try the wet sand by had but if I decide to try the DA on a test panel I would like to know which one to consider.

Thanks again,

SAM

color sanding

I have a DA but I don't use it for color sanding so I can't help there. When I color sand over orange peel I start w/ 600-800 grit, water and dish washing soap till I cut the peaks down some; I am careful not to use 600 if I am getting close to the valleys. Post 800 grit I move to 1000, 1200 and then 1500 before buffing. If I am out of a grit I just go to the next higher one. Sometimes I buff after 1200 grit. If my clear has orange peel then I spray one additional coat of clear to give me adequate film thickness to sand out the orange peel.

The only time I would use a DA color sanding is when I have done the leveling with the traditional 1000, 1500, and 2000 grit wet sanding. I then have used the DA wet with Abralon 4000 pads to achieve a dull sheen that is very advantageous to final buffing and polishing.
