I know this has been talked about in several threads, primarily in the Foamie sections, but I am planning on using this technique on my wood trailer. I was thinking about Gako roof as an inexpensive simple one step solution, but after talking to a painting expert he reminded me that the biggest concern is flex and sheer at the joints, and cracking of the coating at the joints. Grako is a great product, but it is made for stationary roofs that only flex from temperature changes, not a trailer bouncing down the freeway. He highly recommended the use of Gako (or any product) in conjunction with a fabric. This brought me back to the idea of canvas & Titebond II combo. I understand that for foamies since the skin is a structural component a heavy canvas fabric is important over a muslin type of material, but how about for wood construction? I am thinking that bed sheets will be plenty thick for this application since it is no longer a structural component, and give a smoother finish as well.
Thoughts?
