A friend who worked at the LHS told me he had made cowlings out of paper towels and carpenters' glue. After a number of years and my friend had passed away, I decided to give his technique a try.
The procedure is rather simple. Let me describe how I did it according to my friend's instructions. I experimented with a glass dope bottle by layering the bottle with cling wrap, taping it down snugly. Then applied a thin layer of glue on top of the cling wrap. I carefully laid the first layer of paper toweling, stroking it down with my fingers. Satisfied the toweling conformed to the contours of the bottle, a second layer was applied, followed with a third, until the final fifth layer was applied.
That's it. It was done. Light as a feather. The only drawback is that it has to cure overnight.
When the glue and paper had cured, I sanded the molding and on the first spray coating, it was done. The finish is shiny, no filler, no second coat of paint.
I thought I would pass it along, Wan
