Well watching car shows on tv such as american hotrod and overhaulin' a skim coat is actually for dents you cant see until the car is painted, oh and I know this from experience too.

That would be whats known as a "guide coat", not "skim coat". Thats where they hit it with a very light coat of dark paint then block it back to see the dents. where there is colour left, thats a low spot, that needs a bit of spray putty/hi build primer.

Skim coat it for lazy arse panel beaters that want a high turnover in cars and arent to concerned about what the car will look like in 5 to 10 years time.

The cheapest way to get a nice flat smooth surface it to coat the whole panel in bondo then hit it with the electric sander. Bondo is cheaper than actually paying a worker the time it would take to do some some "real" panel beating.

Zthing, use a high fill primer to fill the scratches in the metal, then sand it back smooth.

My 2 cents.

Often on older cars, like many Zs, a competant body man will do a skim coat of bondo over the whole car. This is esspecially true for cars that will be painted black. This is because over the lifetime of a car the body panels get fatiged and imperfections arise all over the body. You can see this on alot of old cars. If you look at the body at the right angle you can see waves in it. This is even the case on cars that haven't been repainted. Some cars, like ours, have quite thin sheetmetal so this can happen even more easily. My brother is working on a 40 ford 5-window coupe and it probably has bondo everywhere. My brother is planning on putting a skim coat on everything. You cant trust panels that old.

i have two very odd dents on my roof, they are creased in near the door. they are so perfect it looks like it was ment to be there, but it looks terrible if u concentrate on it ( stands out) i havent gotten around to the finishing touches of the body work yet and havent really found out what caused these 2 perfect crease dents but just figured id post considering it was related

My 70 240 has filler on top of the primer just aft of the windshield on the right side and just forward of the hatch on the left side. Under the original paint. The seams from the top to the post and quarter panels are done in lead. As is the aft eight inches of the drip rails over the rear side windows.

If its where I am thinking, there are two places on each side on the roof, each about 2" long or so that is pieced together. They go perpendicular ro the body. I think that is where the rear portion of the car is put together.
