After a week of sanding there is not much of a change in the photos. There is up close a huge change. I think another day of detail sanding should wrap it up. As you see it here it is 28.5 OZ. I must be getting old as in the last few days the primer has attacked my hands. Tonight I noticed my fingernails turning red. I thought I have not used anything red. Went to the bathroom and washed in cleanser and saw it was blood coming to the top of the skin. That's a first I will have to watch it from now on.

I don't know what you're using for primer, but I would assume that most primers are pretty inert once they're dry.
I'd be more worried either about the wet (I assume you're wet-sanding) leaching the natural oils out of your skin (possibly aided by any surfactant you're using) and thereby irritating your skin. Are you using some new product in your water to help keep the paper clear? You may be reacting to that. Or you may be coming down with some other condition that's making your skin more sensitive than usual.
My dad always kept hand lotion around the paint shop. Even in my teens, when I was spending a day wet sanding I'd put that goo on my hands as soon as I washed up, every time I stopped -- it seems to keep your skin in much better shape than if you put it on after everything dries up, and those bleeding cracks just aren't fun...

Everyone will squawk at this but I sand dry. I never could get use to the idea of water around balsa. So I use 4 times as much paper. Cost me about 40 in sandpaper so far small price to pay for such enjoyment. The Zen of sanding. I do sand clear with water and joy soap and 2000 grit sandpaper. After washing and not sanding for a hour its all clear. Strange I only have been sanding non stop for 3 days ya think that might have something to do with it?
The thing about it is after 40 hours of sanding It could use 40 more and 10 more after that. But where do you draw the line? I am not sure I would ever finish If I let it get away from me. Its all smooth and flat but tonight I noticed a hard seam in the fuse I will spend a few hours on tomorrow. I am sure while doing that I will see something else I could improve. Some of you have seen my finishes it becomes a obsession. I am not sure if I have that disorder yet or I am acquiring it.. LOL
I guess I could always sand it all off and start over.

I do the same thing Sparky. As for the seam, I take a small paintbrush and apply primer to the low spots and then sand them back out.

I too dry sand, excepting the clear coat color sanding before buffing,,
In my days,, ( one or two ;D) in the body shop, sanding on primer, I found that dry sanding was actually harder on my hands than wet sanding,, mostly because I ALWAYS wear nitrile gloves when wet sanding,, now that I have gotten into the habit of wearing them dry sanding I have many less problems with my hands being trashed.
I am not sure whether its the dry powder evacuating the oils from your skin, or if its the constant abrasion of the grit on the paper that does it, but dry sanding can be VERY painful,,
Sparky, try wearing some good nitrile gloves next time you sand, if they fit tight it should actually help your feel while you are sanding..

Do as Mark says and don't waste time thinking about it. You only have one set of hands.

As the old saying goes...there is no such thing as finishing a paint job, it is just finally abandoned. I have had airplanes in the front row at the Nats and just don't want to spend that much time & effort doing that again; 17 or 18 points is fine with me.
