Does anybody knows where to find or buy an acrylic resin, for pigments use?, other than Migs acrylic resin...i mean any substitute coz we dont have it here (migs).....really appreciate it......

Try to look for it in the shops for artists. That's where I found it.

A good art shop will carry it. "Acrylic medium" or acrylic pigment carrier. You can also buy big bottles of pure pigment in standard colours (so primary and a few secondary colours, you'd have to mix your own to make MIG style weathering pigments). Actually while you are there buy a set of chalk pastels, they are a cheap and effective alternative to designer pigments when you grind them into a fine powder.

Jason, I checked the web sites of two prominent art supply firms in the US (AC Moore & Pearl Paint) and neither had anything under "acrylic medium." Anyone have a suggestion as to brand name?

Same with bulk pigment: some primary browns would be excellent for making mud in large quantities....

Try Daniel Smith. If you can't find what you want by searching call them and they'll help you.
Here's two, one for pigments and another for mediums, nothing for acrylic resins though.
