You are about to enter a world of completely different modeling techniques. Be sure to wash the parts with warm soapy water to remove the mold release agents that are most likely present. Some tools are needed and some safety training is mandatory. Resin dust is toxic and if you inhale it, it will cause you harm. With this is mind use a good dust respirator - that is something with two straps to hold it to your face and be sure you have a good, snug fit. Okay, let's start. To remove the part from the block I will usually use a razor saw and cut it off fairly close to the pour stub. In other cases I will use my Dremel with a cut off wheel or a sanding drum to remove the excess. This stirs up shitloads of dust so have someplace safe, like the back porch, to work in. Once the big stuff is out of the way you can move to sandpaper. Many people will work with wet sandpaper in water to contain the dust. If you go this way you can take the dust respirator off. I use a large sheet of aluminum oxide sandpaper and work dry. I also have several sanding sticks and diamond needle files on hand for fine clean up work.

Once your piece is clean and trimmed dry fitting is very important. When you feel that you are ready to attach the part you need to stop and dry fit one more time. Now you are ready?? Use superglue to attach the pieces. I use regular (thin) super glue and medium gap filling super glue. I put a drop on a pad of post-it notes and use a toothpick to apply the glue. I also use accelerator to make sure the glue sets right now. This is applied with a paintbrush, not the spray nozzle that usually comes with the bottle.

Okay, let's talk about those acetate instruments. First, paint the backside flat white and let it dry. Use some very small drops of super glue to attach it to the back side of the Photo Etched cover plate and more superglue on the backside to attach it to the plastic base plate or original kit instrument panel. If you are using the kit panel you must and it smooth first.

These are some general guidelines, go slow, study what you are doing carefully. Think about it before doing it. Have patience and take your time. Hopefully a few others will come along and lend their opinions to this thread also.

Swanny has a lot of good advice. I would add that if you have a bent part and you need to reshape it you can dip the part in very hot water and the resin will turn soft enough to bend back into place.

Fill bubbles can be done with model filler or CA glue. If you use the CA sand it down as soon as it hardens. If you wait too long the CA will dry harder than the resin and you'll never get the sanding right.

Resin models are nice because you just have a couple of parts to work with. When you are done mastering resin models you should then move up to vinyl models. Yes, that is the same stuff that is used to cover chairs. NOW THAT IS DIFFERENT!

Also keep in mind, it's more brittle than plastic, so you have to be careful not to flex and break it.
