Well resin is a 2 part liquid that cures in the mold. Plastic or injected kits are produced when molten plastic is forced into molds. The mold for the resin kit may only last for hundreds of shots, but the steel molds for injected kits can be made servicable for just about ever. The main advantage in resin is that rare subjects with a limited market are made affordable. The company producing a obscure subject in injection molding may have a hard time recouping their tooling cost, but the main investment in resin casting is the producers talent. You will have to decide which you like better. I like the way resin works and of course the subjects it makes available. Best regards Woody P.S. Email me if you need more info.

Resin call for slightly different building techniques too. Your normal plastic glue will have no effect whatsoever on resin. You'll need epoxy or superglue. Wash the parts in soapy water to remove the film or mold-release material that was used during the manufacturing process. Prime your model before getting on with the 'normal' paint job.

Parts that are bent can easily be put back into their right shape by using warm water.

Cleaning up and sanding resin parts release dust that is HIGHLY dangerous to your lungs. Wear a mask.

One thing to watch for in resin is that unsupported thin parts may droop over time, like long, thin wings, and some load-bearing parts such as landing gear struts and wing struts and braces may bow. Sometimes it is necessary to reinforce with metal tubing or rod to prevent this. Also, some resins are brittle and prone to crack or chip when being processed during modeling. They can be repaired with epoxy or superglue.
