Hey I started working on my own cowl yesterday and here's what I've done so far.
First I took a TDK pep cowl I made myself and then also bought the plain white face mask.

Then I cut both and combined them with duct tape.

Then I added the nose from my TDK pep cowl.

Then I duct taped the whole mask inside and out.

I even added a flap in the back where I'm going to put Velcro so I can get in and out.

Now I'm ready to start applying the plumbers putty but I was wondering if there's a special kind of paint you used so that it doesn't rub off or fall apart in any way. Also for the areas you didn't use plumbers putty can you still see the duct tape if so can I use something like latex paint or a rubberizing paint to make it all smooth and hide it? Or maybe something even better than I mentioned.
