I finished spraying my fiberglass cowling with the Nelson paint system. The results were less than satisfactory. I must state, for any rebuttals, that the instructions for spraying and surface preparation were followed to the letter.

I had on very small run develop after several sessions of spraying light coats. These sessions applied from four to five very light coats over the period of several hours

After drying for approximately 36 hours I attempted to dry sand out the small run. It went well for a while, then all of a sudden the paint lifted from the surface. I was unable to obtain a feather edge with this paint. I eventually decided to totally removed the paint from the cowling and try again. To my amazement the entire paint job lifted completely off the cowling in one rubbery sheet.

I read and reread the Nelson instruction prior to painting. I used a Binks auto touch up gun at the recommended 30psi. I have a large commercial water separator on my compressor.

This paint is not for the faint of heart. I think that a good finish can be had with it, with a lot of experimentation. I do not know how long this paint remains rubbery, but I found it impossible to obtain a feather edge with it.

I am returning to traditional paint for the finishing up of my cowling. You guys that have had good results with this stuff, I am happy for you. I will never go back to it. As I stated in another forum, I have had better results from house latex on warbirds.

Just my 2
