YES! Wetsanding is supposed to take away all the gloss.
The purpose of wetsanding is to remove all of the orange peel and other imperfections. You want a uniformly dull surface with no gloss by the time you are finished sanding. Some people even use a squee-gee to remove the water and check for gloss on the sanded surface.
When you get into the polishing phase, you get your gloss back and, if you did your wetsanding properly, you will get a mirror-smooth finish.
Hope this helps.

My car looked like total crap after wet-sanding it. You can see how the hood looked in the pic on pg 47. That surface wasn't particularly well sanded either.
After a 'good' wet-sanding the paint should be totally matt and as smooth as a babies butt. Then it will polish up to a mirror reflection provided you polish it properly.

Wouldn't that only work w/ single stage paint? I didn't know that solvents could affect paints that have a catalyst/hardener. Was it laquer? You said 1962 original paint? Quote:
Last night I was watching "Classic Car Restoration" on DIY network; they were restoring a 1962 T-Bird. Anyway, they were planning to colorsand and polish the original paint. Before they did so they did some tests on a couple of fenders that had been painted more recently.
Kevin Tetz did a demonstration to ascertain whether the paint on the fenders had hardened sufficiently to polish. His simple test was to put some solvent on a clean white cloth and lightly rub it across the surface of the paint. If the rag came up with color on it that indicated that the paint had not hardened, if it came up clean (i.e. the solvent wasn't able to cause the paint to get wet again).
This technique may be useful for determining when our roller jobs using Rustoleum are ready for polishing. I guess we'd use mineral spirits as a solvent.
Anyone else ever heard of this?

I saw this too but that's not what I gathered. I understood them to be testing for the type of paint and whether or not it was clear coated. This determined whether they could color sand and polish. If I remember right they were checking for:
1. Clear coat
2. Enamel paint
3. Laquer paint

Since painting/detailing my car has stopped for a while, I decided to play with my track bootlid and rear wing. They used to be white. I have given the thing two coats of the Brightside and that pic was taken just after the second coat had finished drying.

Nope, I'm probably the only guy on the planet dumb enough to say no to a free re-spray.
I have put so much work into learning and practicing my roller painting that I feel like I'm being cheated because of that accident.
I know that it's not rational but most of my pride in my car has come from me doing work on it myself. I have built/installed/tuned a Megasquirt ECU and I was the fourth person on the planet getting the Megasquirt working for fuel and spark on a Miata. I want to be the first person on the planet who has the perfect roller paint job on a Miata.
Half of the fun of this for me is achieving something that no-one else thought could be possible. So there is no way that I'll re-spray.
Tom, I used a 10:1 mixture of paint to mineral spirits on the bootlid. That lid does have a few minor dents in it and the area near the wing supports isn't very flat either, but since this thing is only for the track, I haven't been as anal as I have been with the rest of my car.

Your truck is looking awesome already. I can't believe the difference from your 'preped' photos to your first coat photos. The coverage with the Brightside is fantastic.
When I do my painting I have a clean second 4" roller that I run over each 'finished' panel to remove all of the air bubbles. I don't use any weight with the second roller, I just gently and slowly move it across the panel and it ends up looking really good (at least until all of the dust and dog hairs etc start landing on the paint).

Yeah Tom, I found the same thing with the Brightside. It seems to get to a point where there can be too much paint on a panel and then it just doesn't settle properly at all.
Then to fix it, I've had to sand most of it back off to get it smooth again...

BTW speaking of air bubbles what works best to minimize them?
best thing to get rid of bubbles for me was to either blow on them (careful you don't spit on the car!!!! lol) or just before you load up your roller for more paint just use the weight of the roller only, and really really gently roll over the surface, you can feel when the time is right; when the roller glides over the surface without sounding like the paint is still wet, mind you this is when using the tremclad/rustoleum paint not the stuff your using so i dunno, try it?    
awesome job by the way, please tell me your doing that inside????

Yeah I'm just a few miles north of Mexico and 5 miles off the Pacific ocean, it was really nice when I painted right at 70 I was surprised how fast the paint dried to touch. Could be some of the reason for the air bubbles.
And it was painted right where it sits..
When I was rolling brightside, I would go over it once with the loaded roller, then come back in 5-10 minutes (when it was convenient) and roll over it again without adding any paint. Most of the bubbles were gone on their own at that point, but if not, that would get them and would also highlight any runs that needed to be rolled out.
The trucks looking great!
