Epoxy Putty????

i have some of this stuff lying around the house and have tryed i on a scap piece and it looks like im not gonna be able to sand it because, well it looks like is just not meant for sanding, but i have seen tamiya epoxy and have been told to use epoxy so HOW DO I SAND THIS STUFF????:frog:

epoxy putty are really meant to be sculpted before it cures since it cures so hard. your suppose to sculp the shape close as possible. if you need to sand start with a much lower grit than you normally would(maybe 180 grit), or you can use a file to take away most of the material.

How long do you generally wait before sanding? (after shaping it that is)

depends, some epoxy putty have faster setting times than others. i would say the best type to use would be the smooth type. just smooth it with your hand with some water and theres no need to sand. but im not sure what the setting time on the smooth type.

well i really am not using it for sculpting but more as a large filler. i have to fill in big spaces.:frog:

Why don't you just fill the space/spaces with styrene sheet or strip and then use squadron putty or Bondo spot glazing putty?

;) i was thinking of doing that but i had the epoxy putyy laying around here and wanted to see if it would be a good filler.;)

Now, you know it's not. :)
For a large area, use polyester putty. It start curing in 15 min, and read to sand in 1 hour. It's paste like, and might be messy at the beginning, but using toothpick, you can apply very small amount, and you'll love its curing speed.
