Depends on the paint. Metallic bases cannot be wet sanded. (That is to say, the last coat before the clear.) The only paint I have ever wet sanded between coats was back in the days of lacquer. I have used PPG DBC for nearly 20 years. DT330 and 2000 grit is what I use to sand severe imperfections in the base coat. 600 & 800 grit on the hook-it DA between base coats (except the last) will make the final coat flat and smooth. You can use the hook-it system to sand the clear and then apply 2 more coats (called flow coating) then 600, 800 hook-it, 1500 wet, 2000 wet, coarse cut compound with a wool pad, microfine with a foam pad and finally hand glaze. ALOT of work, but a mirror in the ed.

Bingo..

BTW the point of wet sanding is to help keep the sand paper clear of build up. That is why using a bucket of water to dip and shake out the paper is the way to go.

add a good sponge to the mix to help keep the area wet and clean up the residue

I also read somewhere that a tiny bit of dishwashing liquid in the water bucket will help keep the paper from getting gummed up.

True, it helps to keep the paper from loading up, and provide a bit of lubrication

When wet sanding base colour between coats you need to be very cautious when using dish soap. It can leave a residue that causes fish eyes or other chemical reactions when you go to spray your next coat . Make sure it is rinsed thoroughly.

Also, thought it a good idea to mention that a spray bottle is a better solution than a bucket of water. If you use a bucket make sure you change the water frequently. Dirt/residue will rinse off into the bucket and contaminate your clean sandpaper. Don't be cheap. Change your sandpaper frequently as well.

-Change water frequently
-Change sandpaper frequently (use the same grit)
-Spray bottles and buckets work well following the above instructions

Another few tips that I didn't see:

- Keep a supply of clean, dry rags around to wipe down your workpiece to see your progress. This helps keep from over-sanding the piece.

-Keep some clean water separate from the water you use to wet sand, you can rinse the piece to see your progress, and also use it for the final rinse.

-And finally, if you have to do all your fairings, wait till a warm day, strip the fairings off the bike, hop in your friend's or ex gf's pool and have at it, should go by quick!

Never forget to lubricate...

Also buff a day or 2 max after spraying your clear. otherwise it hardens to much and its a bugger to buff out. all me custom paint jobs i do I spray 4-5 coats of a high solids clear coat the next day i DA sand any orange peel out then wetsand with 2000 girt 3M wet or dry paper then buff then glaze and it is amazeingly beautiful. Show quality results. i use a 5 gallon pail with hot water and a splash of Dawn dish soap in the water, that helps produce a much better finished product. If your painted part is a week old skuff it down and re clear it and it will buff much easier. Would you rather ride a bicycle down a hill rather than up? same concept
