Re: PVC Pipe

...yes, my last two coils I've sprayed the PVC with Dolphs Lamination coating,..spray can. I dont bother coating the windings anymore. When the winding is done, I put a small amount of epoxy around the last few turns on each end, just to keep it from unwinding..........No racing spark problems, but, the aspect ratio has been a little higher with my last two coils,..4" by 23.5". I would think if your coil is that far off, its gonna arc through what ever coating you put on it, and, if you have a very heavey coat, it will make it that much harder for a possible repair,...but heck, I DONT KNOW !!!!
