Ok, we started with this (picture on left).
Yesterday, I noticed puckering on the vinyl around one of the rear baffle rivets on my fuel tank. RV builders will know what this probably means.
I too know this implies a small fuel tank leak, but having long ago adopted denial as my first line of defense, I decided to assume there is grease or 'something' underneath preventing the vinyl from sticking.
Using my utility knife (still waiting on the good knives) and my razor sharp (not) eyeball, I cut a square, ok crude, section of vinyl from around the rivet.
Picture at left shows proseal or grease, but not the blue staining of a tank leak. Could it be that I lucked out?
Only way to find out is to clean up the area with whatever I have available (lacquer thinner today), patch, and watch.
Ok this picture shows the cleanup. I will deal with the swirl marks, etc. before I lay the real wrap.
I had to move around to get the light just right to show this. In fact this blends in pretty good.
But what if I try to inlay the patch using the technique used to repair vinyl flooring?
I removed the excess, gently lifted the edge of the inner section and removed the vinyl from underneath. I laid down the remaining section and rubbed and heated as best I can.
It's one of those things, if you are looking for it, you will see it.
I will leave this on for a few days to see if my luck holds or if I need to stop for tank removal and repair.
One good thing to come out of this is that I have discovered a simple way to find fuel tank leaks, even the most subtle ones. Cut small strips of vinyl and lay them along the rivet lines of the tanks.
With the airplane actually wrapped, you can chose to re-wrap the tank rather than patch.
The following are just more pictures of the patch from different angles. The last three are taken outdoors on a cloudy day.
Next I talk about the ever so important 'paint scheme'. I talk about the scheme I chose, how I resolved my limitations with my wants. et
