Putty spatulas

You don't want to do that. 

The one I borrowed from my wife... the tip flexes like a fly fishing pole.
But I find myself using my old school tools more oftem.
My actual automotive applicators and pre-approved fake credit cards.

Guess I'm stuck in some of my old ways. 

The ones I got are so thick I'm afraid if I try to flex them to pop the putty off it will break them!

Well... my wife thought she misplaced the cheap paint spatula and bought a more expensive one. So yeah... I guess I got my butt kicked    LOL

Those fake credit cards seem to be thinner than the real ones so they flex easier and conform to the model shape better.

Also I let a thin layer of spot putty dry on my applicators. When it's dry I flex the applicator and peel the putty off in a sheet. The little that might remain, I just wet sand off at the sink with one of those scrubby pads or an old piece of sand paper. (I don't throw my sand paper away till all the grit is gone... I'm really cheap ).

Dang it, I never even thought of the fake credit card thing, those would work really nice to... "Your Preapproved to work on a model" I bought a few of the ones from hobbylobby, figuring that I would go through them, but since the lacquer thinner cleans them up so nice, I imagine they will be hanging around for awhile!

JHande, your wife is gonna kick your butt...

I started using one when my wife started buying all those oil painting supplies... shhh 

A few more cheap old time putty spreaders...
The usual plastic applicators or rubber pads sold in auto departments,
My favorite - those useless fake credit cards that come in the junk mail.
I have a bunch cut to different sizes.
