My Vapor has had some issues in the past and I'm on my second rebuild. The first time there was an over pressure issue and the seams on the lower body tube came open so I replaced the lower tube. This time the parachute failed to deploy so I am replacing most of the upper body tube.
There was a painting issue where the new tube met the existing tube when doing the first repair. The paint kinda bubbled and wrinkled in that area. I sanded it down and tried again to have the same happen again but not quite as bad. I decided to just leave it and fly as it was which leads to this repair.
The replacement of the damaged area went great. I filled the spirals and the joint with watered CWF and sanded. Sprayed on some filler primer yesterday afternoon and went home. This is what I saw this morning.
This is the same area that gave me the problem after the first repair. I had wet sanded the entire rocket with 220 before spraying and the rest of the rocket looks great. I am trying to decide what I should do. All I can think of is to sand the area down to the bare tube and try again but I'm not sure if that will work either. THe only thing I can think of is that I must have gotten something on the rocket in that area during the rebuild that is causing this. I don't know how, but I do work in a garage as the parts guy so maybe I didn't wash my hands well enough after handling a part or something. If that's the case I'm not sure anything is going to make this area accepting of the Rustoleum 2X paint.
Any thoughts?
