I have a question to ask

I painted some of my bike parts, fenders and such. 2 coats of black and 5 coats of clear coat.
How do I wet sand? What are the steps I take. And do I have to put on another coat of clearcoat after wetsanding?
Thanks for the help.

I've been doing some some painting recently too. You'll find some good info from Ron in this thread. viewtopic.php?t=4371&highlight=clearcoat

A quote from Ron:
"Okay, use 1000 grit, followed by 1500 grit (both wet) on the clearcoat before buffing. The reason for 3-5 coats of clear is to allow one or more coats to be removed for a super smooth surface before buffing. The buffing restores the shine by polishing the paint particles back together and bringing the oils back to the surface. The smoother that surface is, the deeper the gloss will be."

When wet sanding use the sand paper designed specifically for wet sanding. It is the gray paper and will say wet/dry on it. Use lots of water and try to sand in one direction.

You don't need to clear after wet sanding. A polish will make it really shine after the wet sand.

Thanks Joe
What kind of polish should I use or do I just use a buffing pad with nothing on it?

I haven't done any buffing yet; here is what Ron had to say in another thread.

"I use 3m super duty rubbing compound, applied with clean fingers, or a terry buffing bonnet. You rub in small circles until you feel the compound go from gritty to a broken down powder. It's hard to describe, but you'll feel the compound break down as you rub. Just keep rubbing until the reflections appear. Use pretty significant pressure...more than you might think at first."

I'm glad I asked the question or would have done it wrong.
Thanks again.

No problem. Let us know how it turns out.

Post some photos if you can. :)

All I could find was 600 grit, so I got one sheet. I sanded a small part of the fender then applied rubbing compound, this worked ok, but not the way I wanted. I put some wax on it, and that brought it to an ok shine.

I will start looking for 1000 grit sandpaper on Tuesday and try this again.
