Well, you have to do what you have to do
Who are we to tell YOU what to do??
I only told you what I Personally should do, nothing more. You asked
If you can hold the water out of between the two pieces, no problems!
You can almost make all the patches with a hammer, a vice and a piece of wood.
I think you're creative, so I don't see a problem for you to make all those patches yourself!!
