FSM did a beginners resin article two or three issues ago. You might want to check that out. One of the big differences about resin is that the pour stubs are usually much bigger, thicker, heavier (whatever you want to say) than an injected part. Some are so heavy that you have to cut them off with a razor saw. Motor tools work well on some parts. But a few cautions...Some resins are pretty brittle and break easily with any kind of pressure. (I nailed a P-51 seat real badly by putting sideways pressure on it when cutting the stub off.) And, and make sure you wear a mask when cutting the resin. Especially if grinding or cutting with a motor tool. Resin dust is supposed to cause real havoc with your lungs! Work outside, if possible, when cutting or grinding.
You can expect a pretty large amount of flash on thin or small parts. The manufacturers leave them on intentially.
Wash the parts and dry them really well. Then, make sure you prime them. Paint doesn't seem to grip resin as well as styrene. At least that's my experience.
I'm not a resin expert by any means. These are just a few things I've read or run into myself.
