Wow Bob I'm a bit envious. Your "Shop" Garage is really cool, some nice stuff in there and soooo freakin neat!!?. As for pulling out the '49, it's exactly what I have to do with my TA every time I paint.
Now with that out the way, I'm just wondering. The '56 looks to have a satin finish, is that what you intended?
And as for the pledge, it is definately an alternative to the Rusto Acrylic Lacquer that I have begun to use especially in terms of fumes but I'm not too sure about not clear top coating it ( at least with the pledge only). Really don't think you will get a nice finish gloss with the mixture only.
Just my 2 cents my friend.
