Has anyone ever seen a Home Depot bolt on an airplane ? Or is it just an old wife's tale ?
I would also add, that for a slightly firmer and less spongy surface, you can use the Stewart systems primer. It’s not expensive. I have also considered experimenting with adding marble dust to the second coat of gripper to firm it up just a bit.
We currently have a fella at the airport that has one of these in his plane:I have seen some strange homebuilt airplane fixes. Big hardware store turnbuckle used as an adjustable bracket in the engine compartment. Telephone wire. Trailer tail light wire for strobes.
Just for the fabric. There is an ideal bit of firmness that the fabric ought to have. Strait gripper and latex in my opinion is just a bit shy of that, leaving it a little spongy feeling. As I wrote above the Stewart primer seems to take care of that, and white it’s not expensive, if I can firm up the gripper a tiny bit while still keeping its flexibility, then I have cheap winner.ToddK,
Are you thinking about doing that for the aluminum & steel parts? Anything that makes the paint more rigid on the fabric would be counterproductive, it seems to me.
