Sanded too much!

[enkeivette]

So I sanded off the first 6 layers with a DA, leaving only the original primer. Then I started to take off the primer with a rigid and a flexible sanding block. As SMYDA has said before the original SMC was not perfect and sanding reveals the low spots. So in trying to get rid of every last bit of primer, I've started to see fibers in a few places and there are still spots of primer in those places!

So where do I go from here? Do I need to get rid of every last bit of primer? Should I attack the spots individually (waving the body) or should I leave them alone? Should I go over the fender where I can see fibers with some filler? Or is it not a big deal?

 

[SMYDA]

When I first started doing body work one of the toughest things I had to learn
was when to STOP sanding. I would wipe it high then sand it low ....... over
and over and over :lol:

When you hit the bare glass ... STOP ... the dark spots are areas that now need
to be filled. Do not try to sand the bare glass "straight". The object is to not
make the body any worst than it already is .... (originally).

Sand just enough in the low areas to remove the Old primer.
Spraying the entire car with products like "Slick Sand" is the way to remove
these low areas. Your now leveling the "Slick Sand" and not the fiberglass.
(If you leave a small spot or two of the old primer before applying "Slick Sand"
I don't think it will hurt anything, just so that you have the majority of it off.)

Adam, I wasn't trying to be a smart arse a few months ago when I said to use your hand when you were talking about stripping your car with a DA sander. I thought you'd end up with the result you have now by using a sander.

I would also have said the same thing about using your hand if you'd asked should you use a rigid sanding block, especially that close to the glass...

How fast can you back peddle?

Can I stop now?

Your initial response was incorrect, I was asking if anyone made a flexible power sander. You said no, the answer was yes. I'm still very glad that I used a flexible power sander to strip the car. There are two spots over the fender where I went too low, the rest of the car is fine, it will be easy to skim over those spots with some glazing putty. I'll just be more careful and less thorough over the rest of the car. There were 7 layers of crap on this car, had I used my hand I'd still be on the 2nd layer. And I did go over this fender with a flexible block.

But yes you can stop back peddling. Haha. :friends: I must have been in a bad mood when I wrote that, probably because I had only been sanding by hand at that point! :crylol: BTW, I'm told that sanding by hand can put grooves in the body as your hand does not apply pressure evenly.

Which is why my car looks so junky, I refuse to repaint/repair because even IF I got it looking right, some asshole will mess it up for me.....parking lot, vandals, crash into me....happens EVERY damn time I have a decent/perfect car, some freeking nitwit messes it up....

so I leave it the hell alone, cheaper that way.....

Yeh, I think it was Glen Smith, Mr.Blue that agreed with me, in the parking lot waiting for others to show up....somehow that topic came up in conversation.....

My C2 has been primer since 1973. Three times I tried to paint it. Three times it got hit just BEFORE painting. One time the rear quarter was hit by a 18 wheeler. If I don't get it ready to paint I don't get hit.:mime::huh::tomato:

I was sitting in my car reading a few years ago, this lady pulls up next to me, parks, gets out, thunk... she opens her door into mine. I get out, thunk, again!!! I confronted her, she was surprised to see me get out. She acted as if I was being rude.

Just recently I was driving my dad's car, parked in a lot, on slight grade. As I'm walking back to it, slap! Some c*nt in an expedition let her door fly open and hit the car. She doesn't try to stop it or even move it after it hits. I walk up and yell at her "Are you serious?!" Fortunately it only hit the front of the sideview mirror and didn't do any noticeable damage.

Some people are just in their own little world.

i was at the local car show and this guy in a beater gto opens his door right into a mustang gt350. then when confronted the guy actually has the nerve to open the door again up to the mustang to see if his door lines up with the paint chip

The flexible sanding pad is "new" since I last painted a car but I still think I could have stripped it (7 layers of crap and all) just as quick by hand. And you're right, sanding by hand CAN put grooves in the body, when done incorrectly - if you sand by hand in the direction of your fingers, you WILL leave grooves. Sanding with your hand sideways, you won't get grooves.

I spent over ten years doing body work and painting cars. If I was stripping back to bare steel I'd use a wizzo (random orbital sander) and get the paint and (if any) old filler off quick. Doing anything to a glass car or glass panels, I did by hand.

What grade paper had you been using when you were in a "bad mood"?

Who knows, 250? Haha. I knew nothing at that point. I don't see how you think you could take off 7 layers as quickly by hand as with a DA. You must be really fast! I've done a few spots by hand where I can't get to it with a DA and I use 100-60 grit, depending on how much is left.

What year is your car Saudi?

 

[saudivette]

Mine's an 82. Once I've done the interior, I'll do some body mods I have in mind and then I'll be taking it into a panel shop. Whether using a sander or doing it by hand, it's too damn hot out here to be rubbing a car down and the cost of labour is dirt cheap :thumbs:

 

[big_G]

What we do at my shop is if there is a little original lacquer primer left (after sanding) we use a Scotch-brite pad and lacquer thinner and rub it off by hand. Use paper towel to remove any remaining loose primer.

 

[Belgian1979vette]

My body had its primer already partly removed. I sanded it all out and yes the fibers were visible. I filled when necessary and sealed it off with the epoxy primer and worked from there on. No problems. The fibers are not visible.

Bingo! If you sanded into the fibers :stirpot: you will have to seal them back up or they will show through your paint job later down the road. You don't need to get all the primer off because I would hope that you are planning to seal the car with some sort of epoxy. Good luck!
