Hi

Good day Harrier. I have done a bit of resin casting. I use a RTV (Room Temperature Vulcanizing) rubber for the master. Two part, just add part "a" to part "b", mix and pour. As to the master, I have only done stuff like packs & veh storage. I glue the master on a piece of plactic card and build a box around it. I have found a 1/4" clearance all around works well. I then pour the RTV into the mold. A bit at a time and I brush it onto the master. Fill the rest of the void. I move the mold around, tilting it it to allow any air bulbs to rise to the surface. Once cured "unmold" and allow to fully air cure. Mix your resin (part a & b) and gently pour into mold (reduces air bubbles). once hardened gently flex mold around sides to release the new part. Again allow too finish air curing. Remember the RTV usually has a long "work" time , while the resin can have a very short "work" time so you must be organized. As to brands, I have no idea what is available in your neck of the woods. The molds usually last for a couple of dozen castings. Find RTV rubber that is flexible and resists tearing. Long windened but hope it helps.

Micro-mark has everything you'll need. I think their website also has a short tutorial. (www.micromark.com)

Here is the link to the feature on here about resin casting that Matt was talking about.................. https://armorama.kitmaker.net//features/469&page=1

This pretty much sums it all up. Matt has way more experience then I do, as I am just recently playing with this. However, I found this truely helpful. When you need resin and RTV silicone, there is a guy on Ebay called "Aeromarine products" who sells some nice stuff to my experience. you can even call him if you have questions or need items. The Phone # is (877) 342-8860. Hope that helpos you out. If you have more questions, ask away!
