Default Berger panel prep...

I was wondering if anyone could point me in the right direction for a post that details the steps used to strip and prep a fiberglass Berger panel for paint. I'm sure it's fairly simple, but this is my first attempt at any kind of body work.

Should I wet sand it or just dry sand it?

1.Prepping for primer
a.sand with 180
b.sand with 320
c.clean with a wax/grease remover
2.Primer Stage
1.spray 5 light coats of a good high build primer like duplicolor makes
2.let dry, preferably overnight
3.WETsand primer with 400 grit
4.wetsand primer with 600 grit
5.clean with wax/grease remover(the panel should be smooth)
3.Basecoat Stage
1.Spray 5 light coats of basecoat of your choice
2.Let dry overnight
4.Clearcoat Stage
1.If using a gloss basecoat use regular duplicolor clear, if using a semi-gloss or satin basecoat use a low-gloss clear.
2.Spray 5-7 light coats of clear
3.Let dry overnight
4.Wetsand with 1000 grit
5.Wetsand with 1500 grit
6.Wetsand with 2000 grit
7.Use rubbing compound preferably on a d/a like the portercable 7424 and polish, the panel should really start to look good at this stage. I use menzerna powergloss compound.
8.Use a polishing compound
9.Enjoy!!

Now this is not the only way and probably not the best but this is the best way that I know of for getting results. Ive done a berger panel according to the write-up on here and it came out looking like ****. Using the way described above I painted my slp grill below. It seems like a lot of work but the result is well worth it.

If you are doing clear follow the instruction above especially if using spray paint. 3-4 coats of clear like the can suggests will not work. 5-7 is a good number, the stuff just stays too soft and with too few coats even 2000 grit could cut right through it.

Do I need to sand it all the way down to the fiberglass or can it be scuffed up pretty good and primered?

Scuff it up enough to remove all the gloss and ensure it is smooth.
