Just getting started on the tail cone, which has me thinking ahead about priming it.
So far I've been using SW P60G2 internal on the other emp. parts. It works OK, but it seems like it's not the most durable and is very susceptible to scrapes and scratches. No matter how careful I am, it seems there are always minor scrapes and dings from the squeezer and/or bucking bar after assembly. I usually then go back and touch-up those areas with some rattle-can primer before closing up or after final assembly. It's not pretty, but since those areas will likely never see the light of day again it doesn't really bother me.
But this has me thinking about the inside of the tail cone. It seems this area will see a lot of traffic throughout the build as servos, batteries, cables, etc. are installed, adjusted etc., and even after flying as a result of inspections and so on. I just envision how scratched up the P60G2 could get in there over time, or how many layers of rattle can touch-ups will build up
.
So I've thought about perhaps top-coating with jetflex or something, or perhaps switching over to an epoxy primer of some sort for this area which presumably would be more durable? Probably whatever I do here will also be good practice for whatever I end up doing inside the fuselage when the time comes.
Those who have traveled this road ahead of me, what has your experience been?
