Fuel Tank Leak test using Vinyl Wrap
Hello,
I am playing with vinyl wrap as prelude to (finally) upgrading my paint scheme from primer and bare aluminum. I have started a blog (of course) detailing my start to finish vinyl wrap adventure (rv8wrapup.blogspot.com) but have come across something I should pass on.
If you want to find fuel tank leaks, I mean the really tiny ones that do not leave a blue stain on your tank, place a strip of vinyl wrap (3M 1080 series) along the rivet line and leave it for a few days. It will peal off, at least mine did (test first on your plane if painted). Below is what you see over a leaking rivet. No balloons, dunking, soap, baying at the moon, etc; just a few gallons of fuel and vinyl wrap. You can use a 'big hole' paper punch to make vinyl wrap spots to place on each rivet to test for leaks which will minimize vinyl waste (it's expensive).
This is a vinyl test strip on the outboard aft edge of (pilots view) right fuel tank. The leaking rivet is clearly visible. Assuming you have fuel in the tank.
It is a good test prior to painting as well.
If you are curious about vinyl wrap from the perspective of one who is clueless about it, then you might find my blog of some interest. Better yet, buy some small sections and 'play' with it like I am.
As for my leak? I have applied thread blocker green to rivet in hopes it will miraculously seal the leak because frankly, I really do not want to mess (again) with fuel tanks and pro seal.
Hope this helps.
