poly puty with hardener

i just bought my first putty for my sractch build parts :icon16:
this is use in the car knocking and spraying industry ....

is it ok for models?
i tried some and seems to be easy to use and sand them

oh yes
it is brown in color.....
the hardener is yellowish...

lots of folks use automotive poly putty on their models. It should be fine.

thanks bro :)
my first poly putty :D :icon16:

i have a question
when we already pfill the car model with putty and we sprayed the primer and paint. next realise the color is not the one we want, can we put the car back in castrol dot 3 brake oil? i am scare it will damage the parts that are being filled.
