Anyone know where i can obtain the proper color of paint, the same color you see on F1 grenades and PG rockets.
You just got to be really careful when making the molds, there is a trick to preventing air bubbles. Tapping the side of the container with the material, and pouring slowly and carefully, will eliminate most of your bubbles. Same for tapping the molding "box" or whatever container you are using for actually making the mold itself. Plus, if you are using modeling clay to cover part of your object, it helps to insert or create shapes that can be used as a "key" or "guide" of sorts, so the mold fits together perfectly.SturmGrenadier said:Yes John the Bulgarians use a dark OD green.
Doug, it gets a bit expensive especially when trying to make the molds....one degree off here or there or a big air bubble and you've just wasted a whole thing of mold making material.
Two part resin ya have only minutes to pour once mixed before it starts to set and it gets hot....no, HOT. Ya gotta be carefull with that too cause if your stir too much ya get millions of little air bubbles.
Its a real time consuming PIA and I abandoned the project. Being a perfectionist doesn't help either.
Creating the molds themselves can be a difficult process requiring the elimination of air bubbles as well.davehal9000 said:Invest in a painting pressure tank from Harbor Freight. Pour the resin into the molds, place the molds into the tank and turn on the compressor. The bubbles will be compressed and pushed into the center of the resin and away from surface detail. Saved me a TON of time and resin. A cheap fix!
For creating the mold itself, brushing a small amount of silicone rubber will prevent the mold from getting bubbles.davehal9000 said:That's exactly what I use. Yeah, impossible for use in molding a PG-7 round but plenty big enough for a grenade. I do also use it for molding as well as casting. I seldom ever have bubbles and if I do it's because I've been horribly sloppy, breaking the usual molding/casting rules in eliminating bubbles. When I have had that one rare bubble it's been easy to fix, unlike my days before using the paint pot.
Thank you, you are the man!big_johnson_92 said:I found this color Rustoleum at Walmart:
They call it fern. It seems pretty yellow to me.
