I'm stripping a '57 Chevy hardtop, and found that the last of four paint jobs was done using a bright green putty... probably 2-part. I am trying to date the work.

Anyone use it? Is it still around?

3M sells a green spot putty to date.

Thanks. If you know approximately when it came out, that would be of interest.

The top color is probably a catalyzed layer, judging be how it is coming off, so that would probably be no earlier than the mid eighties. As faded and deteriorated as it is, I would guess it is 10-20 years old.

I wouldn't be surprised to see some dinosaur bones in the first couple repaints! :-)

It's 3M acrylic putty first produced and marketed around 1981.

Thanks, Judging by the fact it's catalyzed... has that putty... and the badly deteriorated condition of the paint.... I figure 80s to mid nineties at the latest.

They still sell it. I wouldn't use it, maybe only on model toys....

1k acrylic spot putty should never be used. It shrinks up no matter how long you have it sitting before you sand it. Just not good stuff. I actually saw a guy skim coat with it to take care of pin holes. I would sand it off.

Just to make things more clear..... I am not going to use it. I just wanted to know when it was made, so I could "date" a paint job.

that 3M acrylic spot putty was worse than garbage, it's a curse from hell. It came as green and pale blue, neither is worth the trouble they cause.

"1k acrylic spot putty should never be used. It shrinks up no matter how long you have it sitting before you sand it"

It also has the nasty bad habit of swelling everything under it to the metal, leaving a lovely 3D pattern of your whole swipe mark showing thru the finished paint work days later. Tons of fun. Used it once, never again.

I have heard other body people say this also.
