the resin is a 1 component. the setting time is a few ours in the "cold and dark" and about half an our on a warm sunny day. I usually apply it last thing in the evening. and next morning it's set. to make it compleet
the putty I use takes about 10 to 15 minutes to be hard enough to sand.
the sprayputty takes about 5 to 10 minutes to set.
at this stage I use 180 grain dry sandpaper. just befor the colorpaint. I use wet sandpaper 280 of 400grain.
just as importand. let the sandpaper do the job. don't push to hard.
and this is for the torpedo.
the 4x4. I'm going to experiment with it. so failure is an option. it will get acrilic paint, form a tube. and I'll brush it on. It will also get some 2 component rush in some places. this way it's easiers to weather the truck.
