Can you sand clear coat? It was my first time using a Two stage type Omni paint with Omni Clear Coat with Slow hardner..The Base coat went on just fine...but never spaying clear before, I got a few runs and orange peel in some places :oops: ...any advice from some of the experts out there?
BTW, any of you looking to buy a Good Spay Gun that wont break The Bank...The Devillbiss Finish Line 3 is one AWSOME Gun for about $120 Bucks!

Thanks Everyone!

Thanks for the reply.
How long should I wait to wet sand? I used a Slow Hardner in the Clear Coat
Do I use 800 grit?

After wet sanding do I spray more clear or use polishing compound and buff it out?

Thanks again!

Wet sand with no rougher than 800 depending on how bad the blemish is. Step up to 1000, 1200,1500, and then 2000 (you can skip some of those but the next finer grit will take more time to get the previous scratches out. Then you need to buff it. Be very carefull on edges both when sanding and when buffing. There are many different grades of buffing compounds too. I suggest you go where you bought the paint and ask their advice on compounds. You can wet sand clear the next day, but its best to wait a few days for it to cure more. Leave it in the sun to speed things up. I wet sanded polyurethane single stage the same day with good results, your clear is polyurethane too.

Runs in clear are kind of a standard thing for new painters. You paint the base and it goes on so evenly and nice.Then do the same thing with the clear and end up with runs and sags. The next car you paint I will bet you end up with a dry clear coat. Its better to have some sags and runs than to be dry. Even guys who have been painting for ages get sags and runs once in a while.

As for wet sanding, good info posted in response. Do yourself a favor though, and go a garden center and get one of those garden hoses with the holes all down it. Lay it over the car and wet sand. Dont ever let a car that you are wet sanding get dry while sanding. Also, make sure you wash the car very very well before buffing it out. I'm very partial to 3M buffing and polishing supplies.

Just for a point of reference. . . I was watching "American Hot Rod" on tv the other day and their super body shop guy (Charlie?) was stating how thick urethane was and that it went on kind of gloppy. I think they were working on the Aluma-tub. It was the black 32, aluminum roadster. I was flabbergasted to see what his paint job looked like before color sanding.

Thanks to all for your input...One question that still bugs me is. After I wet sand the car and wash it and then buff\polish will the clear still be very shine and good looking? The Base color went Great....even, and flat...So I am still holding on to HOPE of a good looking Two Stage paint job

Thanks again.

Even after I buff it and use the swirl remover?

I did my car the same way with a base/clear paint.
Wetsanding is mandatory and so is buffing.
Use GM Extra cut for the 1st buff then go to the 2nd final glaze.
Carefull not to burn the clearcote. It's easy to do. Just keep the buffer moving and use a professional buffer, not those Auto Zone kragens kind and you will have a great paint job providing you sanded all the runs and orange peel out first

If done right the clear will look much better after wetsanding and buffing. For a reference, a typical car paint job is not wet sanded. A show car will be wetsanded and buffed.

I started some of it today I started will 1000 grit it didnt seem do be making much difference I switched to 800 grit and used Mequires #1 Mild cut with prof buffer...WOW! What a difference... the clear is flater and very very shinny,,,I could not believe it! cant waint now to finish and put on the swirl remover and Hand GlazeI am glad now it did sag ang orangr peel some, Because when I noticed it was doing that I started putting it on pretty thick...because I knew I was now going to have to do this part.....So it gave me a little more skin to work with.....I would have had a tough time with this if it werent for each of you how gave advice..I hope I can help each of you one day...Ya all are a Great bunch of folks!

Thanks Guy's!!! BTW...The Shine Looks A FOOT Deep!!!

Hey, sounds good. Post some pics of before & after, sounds inspiring. I'm planning on a home paint job when the time comes on my project so I'm always keen to see other peoples results. Keep up the good work.
