Your review of the wheel?
its smooth really smooth. you buy them in different grits and this is a 120 grit. i have decided to put more effort out with a finer grit then go faster with a coarse grit. i want no sanding scratches that i have to fill. i have only done that little section so far. my 4 minute of use observation is that the final surface of the steel is amazingly smooth. i will keep you posted as i figure out the best technique

If you plan on using epoxy primer it's better to have some 120 grit scratches for the "extra" bite ... I usually shoot my epoxy over 80 grit , two coats regular urethane primer fill all these scratches, the the usual block sanding ...

laquer or urethane, doesn't matter.... don't shoot the primer over a polished surface, it's not as good as a rough surface when it comes to adhesion.
are these disc the so called roloc discs ??

these are made by 3m and I got them from east wood, scotch bright bristle disc, the grit is 120 grit and i think i will take a traditional 120 grit paper on a DA sander and use it next to a spot i used the disc on. and see if there is any difference. i do want good adhesion.
1 hour tonight.....did I mention I hate sanding...
first with 80 grit paper on an electric circular sander then with the 120 grit 3M bristle sanding disc. disc started at 16mm inside and 16 mm outside and 25 mins later it was down to 14.5 mm outside and still 16 mm inside i think i eyeballed it to be somewhere around 10+ sq ft

oh man thats a sweet ride.... an early 50s buick? that thing will take forever to sand....you will come out with arms like a gorilla. I bought my first MGA after painting a 65 chev fleet side....and i bet your ride has more sheet metal.
well today another hour of sanding...did i ever mention that i hate sanding
out comes the window, i did about 30 mins with 60 grit and then 20 mins with 120
the bristle disc had 20 mins of use and at finished 13mm inside and outside

hate to sound like a broken record but honestly: if you get these cars outside and use a sandblaster you'll get the paint and the rust off in no time.... you can buy cheaper than this ALC blaster that I got, Allsource is the ALC knockoff brand.... you can get into all the corners and it leaves the perfect surface finish for primer.... if you put a 20x30 tarp under the car you can even re-use the sand....
that Buick reminds me of "christine" ... what car was that? was that a Buick ??

Its future includes new suspension, and a 900 hp twin turbo grocery getter motor... maybe a 3" chop and shiney paint.

I have done the sand blaster thing before on a Jeep cj5. when i left NJ i sold all the sand blasting stuff. I just was not all that impressed with doing it in a back yard set up. It may be that we have too much moisture in the NE and the sand or even the specialty abrasives clump too much. so this time its just the old fashion method. these cars are really small.

yes, moisture is a big problem especially here in FL. I added a drain pot at the inlet to the blaster and I'm using the biggest nozzle they sell.... uses a lot of sand though.... for my 4 VW rims I used about 250 lbs of sand.... was very quick though, maybe 30 minutes per rim and that included unclogging the nozzle a few times....
the whole process is rather nasty - the dust goes everywhere and you need a really good respirator....

lol
I'm really fortunate with my neighbors.... but I try to sandblast or paint when they're not home
nice progress with the bristle disc, I'll have to ty one of these ... not too long ago I bought a few stripper discs at Sears - they were on sale, like 70 or 80 % off so I bought all 6 they had left for like $4 each
... these discs are for use with an angle grinder, they remove everything down to bare steel .... good stuff.... don't last very long though, at 12 bux a piece it would be way too expensive stripping an entire car.....

I'd recommend getting a blasting cabinet big enough to do wheels. Even the cheap Harbor Freight example is pretty nice - my dad and I recently got one of those after getting tired of the little benchtop we'd been using for over a decade. It won't help out with body work, but at least you can do some pretty big items while keeping things a lot cleaner and using far less media.

so lets say about 6hrs today of play time....i was surprised how long it too to remove everything

I dont want to highjack but...
Even cheaper, build one.
Cost me 2 4X8 plywood, two toilet bowl flanges, pair of long sleeve gloves and a cheap sandblast gun.
I build it between the two garage doors, it's 30 by 30 and painted the interior white.
By the way the paint holds on pretty good.
works ok, but got to keep the humidity under control, cheap gun tends to clog up.

same red as the bottom of my sons camper that we painted 1.5 yrs ago, the vin is coded for the color and we did a test sample on the original lacquer on the car and it was really close. his camper is outside year round and the paint has had no issues what so ever and still looks great. these Mg guys are like NCRS types so this time i am going with the flow.
