Hi, I have never used these release products you mentioned, but I would hesitate to use only a paste type wax as a mold release. Release wax is basically used for "around the edges" . Although it is possible to use only a wax with several good coats, Your best bet would be wax then apply PVA for your first parts and to make the mold. There is nothing worse than cutting up your plug and mold and throwing it in the garbage because it dident release{I learned this way}. I suggest that when you make your mold you first wax it with Partall brand wax, and then use their PVA lightly sprayed on in several coats. This never fails so long as you get a nice coat of PVA on the part. After you have your molds the first couple parts I still use the PVA, then switch to a semi-permanent mold release after I re buff them. If your not planning serious production I would just use the PVA. Its easy to spray, cleans with water and does not hinder surface details like panel lines etc, and it is almost absoulutely positive that you'll get a good release every time. This is the system I use on my molded parts, It is definately not the only way to do it, but I have found that it works very well for me every time. I'm sure that your fuse would not be too complex to mold, but you will think so the first couple of parts you make! Expext a nice fuselage the way you want it after 4 or 5 or so parts. If you havent layed up a fuse this small before, on your first one your going to have fun{frustration}, but every time after you learn something and pretty soon you can do a perfect one in your sleep. Hope this helps out some. Good luck and have fun, Rick
