It's not light compared to aircraft Dacron, doped. It's also damn near
impossible to bond to (Polypropylene). Most manufactured stuff using
it (post office bins) use "spot welds". Bicyclists using it for
fairings mechanically fasten it. Contact cement is the only
sem-reliable way to glue it that I've found. Paint doesn't stick to it
for S__t either. It doesn't do well in the sun.
Need I continue? It's a fun material, but not to cover an airplane!
Veeduber tried all sorts of things, and settled on uncertified Dacron
from Aircraft spruce, lacquer from Home Depot, aluminum paste, and oil
based enamel, also from Home Depot. He also outlined how he came to
his conclusions, and how you might come to your own. Go to
