Squadron putty

One is green, and the other is (I think) white.

To tell you the truth, I haven't the foggiest idea. I've only seen the white in the LHS. I have a tube of white and it works, but it is fairly nasty stuff to work with. Don't get it on your skin and use good ventilation!

i have never noticed a  difference

One of them is finer blend than the other. Your guess is as good as mine as to which on is the "finer "stuff because they seem to work the same for me.

Green, white, they're both junk unless you're filling in a gulch and will later cover it over with something else.  Besides, you can get exactly the same stuff at any autobody supply shop in a huge tube at one-fiftieth the cost.  Ask for nitrocelluose filler.

For truly sandable, featherable filler, use Mr. Surfacer.  I'm finished with that Squadron crap after too many years of spray-painting finished models and then going, "Oh, yeah, so that's exactly where I put the filler.  Thanks a lot, Squadhole..."

whit is supposedly finer grade.

both of them seem (no pun) to be visible  after paint though. i now use mr. surfacer for most things. it works much better.
