Update: We have put enough coats on for good coverage(7), but I didn't make "Pro". Last coat definitely was the best, using Chucks wet roll & dry roll method.
Unfortunately, there's a slight orange peel, but can only see with lights & closeup.
So, can I just perfect it with the 1500 sandpaper & 3m Perfect-It? Does the 1500 leave any scratches?
Also, what KIND of 3m Perfect-It? I googled and found several, compound, swirl remover & polish. West Marine had Super Compound...if I use that, do I need to sand?
And then just follow instructions or any special tips?
If I goof this up, then I'm facing another complete sanding and painting...

Any detailed hints will be TREMENDOUSLY appreciated!
