Should be getting my first Verlinden resin AM kit this week.Here are My questions reguarding how to deal with them.
1.how should they be cleaned and trimmed?
2.Do they need to be sanded before paint?
3.Should they be primed?
Thanks,Jeff T.

Resin101 - Not all that hard

1. Can be cut with a razor saw, this is the best method to remove molding sprues. A good xacto knife will work too.
2. Can be sanded to clean up and mold line.
3. Before painting or priming, clean with a good dish soap, I use Sunlight, I find it cuts through the mold release agents very well. There are some resin release agents that require a little stronger cleaning, I recommend Sylvain ResinPrep http://www.isp.ca/sylvan/resinprep.htm you can sometime find it in the Model Railroad section. I have used this for years, and love it, plus it smell like oranges.
4. Prime, it is best to use an enamel based primer, I prefer Tamiya Fine.
5. Use CA or Epoxy to glue, I use Gorilla Super Glue.

After those five real easy steps, you can continue like you would with plastic.

As Kevin said, cut the pour block off with a razor saw, finish with a sanding stick, trim any flash with a #11 blade.
Contrary to some urban legends, resin is not toxic. Resin dust is not poisonous. It is no more dangerous than styrene dust, saw dust, or household dust. You don't need to wear gloves and a mask while working on resin.
I spray resin down with Windex and rinse with water, just like I do styrene. Makes them squeaky clean. I don't always prime, I usually go right to paint.

Thank you gentlemen.One more question,better to sand wet or dry?Jeff T.

I dry sand it. It depends how concerned you are with dust control.

Thanks again Guys,I just picked the kit up at the Post Office and took a look.It does not look like the parts are very flashy,so prep work should be not too bad.Jeff T.

Maybe I'm doing wrong, but I've never washed my resin kits. I just just, sand then prime with a can of cheap-o Walmart flat gray primer. Works perfect for me, and results look great
