If you are looking for a resin to do a proper dip and bake on a transformer or coil, and don't want to buy it by the 5 gallon pail, Cactus Juice is your answer! As far as I can tell, that's actually what this stuff is for in the industrial world... You will need to set things up where you can either pull vacuum on your coil or let it soak in the resin for many hours (I went overnight). Be aware that this will NOT turn it into a brick; it IS going to glue everything that is close together into one piece, but large cavities will drain out. It will take a LONG time to get your whole transformer or coil hot enough to set the resin; you MUST measure the temperature of the iron! It took more than an hour to get to temperature on mine. The adhesive used on Kapton tape softens when exposed to Cactus Juice and ends up slippery rather than solid or grippy. This isn't an issue for things taped internally, but you may notice it on the end turns. Fiberglass tape shouldn't have this issue, as the Cactus Juice can penetrate the tape itself. I didn't test this, so YMMV!
I used it on my Magnabend build; self bonding wire is VERY difficult to get. Regular magnet wire is easy to get... With this resin, you can do a proper job with plain magnet wire. The biggest drawback is that you must use the actual steel components when you bake it to ensure that the coil is where you need it to be; you won't end up with a free standing coil. TEC Bond 7718 Polyamide Glue Stick (gluegun.com) is a good choice for attaching the insulation for the end turns after baking; it melts well above boiling water temperatures, unlike every other "hot only" hot glue I tried. Epoxy works too, but you end up having to do it in many batches with lots of waiting on glue to set. I think it was 9 batches over two days vs about 20 minutes (I did one end each way).
