I purchased your product recently and am using on my 2000 MPV trying to get it ready for sale.  I've already read some posts here and have picked up some useful tips.  I do have a few specific questions though that I'd like to ask.  If anyone can help, I'd greatly appreciate it.  Thank you!

1.  I'm still on the basecoat, haven't gotten to the clear coat yet.  I've noticed for each coat, there are tiny imperfections that occur.  Is it necessary to sand/compound between coats, or should I just wait and do it once after I'm done with all coats of the base coat?

2.  I think I've confirmed this by reading other posts, but it is possible to get out paint that spread outside the scratch by using rubbing compound?

3.  It sounds like you recommend rubbing compound over sandpaper, particularly for small scratches...correct?

4.  When I did the color match check that you mention when I got the paint, it seemed right on.  However, when I actually put it on the car, it seems a little darker then the actual paint.  This is just with the basecoat.  I'm guessing/hoping that the clearcoat will brighten it up and make it match the rest.  Is this what will occur or should I be concerned?

5.  If using basecoat and clearcoat, should you apply basecoat until it is even with surface, slightly above, or slightly below?

5.  Based on what I've read on here and directions on your site, the best approach after cleaning, primer, etc is:

1.  multiple layers of basecoat
2.  Sand with polishing compound after all layers are complete
3.  multiple layers of clearcoat
4.  Sand with polishing compound

Are polishing compound and rubbing compound the same thing?  I have I need to get rubbing.

Basically, if possible it sounds like I should bag the sandpaper, right?

Lots of questions, I know.  But thanks alot in advance for any responses.

1) The smoother the paint, the better the finish. You can use rubbing compound between coats and this will help smooth out the paint.

2) Yes, use rubbing compound to remove paint without damaging the surrounding original paint.

3) Yes, we like rubbing compound as it doesn't damage the surrounding paint like sanding will.

4) If it is a metallic paint, it can be somewhat darker depending on how the metallic flake lines up. I didn't know if you are spraying or not, but to have an exact match, metallics need to be blended into adjacent panels but this is only possible to do when spraying paint.

5) Tell me exactly what you are repairing here.

6) Polishing compound and rubbing compound are similar but polishing compound is much less agressive than rubbing compound and can be used after you have used the rubbing compound if you want a deeper shine. Think of polishing compound like 4000 grit sandpaper compared with 1000 grit for rubbing compound.

As you get a little experienced repairing scratches, etc., it does get easier.

Thank you for the input.  I do appreciate it.  It is a challenging thing, I must say.  The scratch I originally got it for, I didn't do a very good job.  I was repairing a scratch that I believe we got at a parking lot...or from one of my kids toys(in the garage).  It was "L" shaped and was down to the primer.  I think the mistake I made is that I put too much paint on.  Too much base and too much clear.  I rubbed the hell out of it until it looked at least OK, but not enough to get all the stuff off.  You can steel feel the hump in it when rubbing accross with your hand.  Decided to leave as is.

Other ones on the main body came out better.

The one thing I did notice was that the color doesn't really match right for the bumper.  Not sure if it is because it doesn't have flex, or because the bumpers are just so worn.  It ends up showing up much shinier on the bumpers.

Thanks for the insight.

Sometimes the bumper can be painted a slightly different color or it may have faded if the paint seems to dark.

You can also go to a detail shop and have them use a power buffer to smooth the paint down as it's quite difficult to do this perfectly by hand.
