Thanks Charlie, I am still in the covering process, and I am doing some tests in an old Venus wing (which is not in use anymore but it is great for the testing purposes). Right now I am running a test with Rustoleum, but it need many coats of painting (5 so far) to start covering the fabric pores.
I went to walmart and bought the water based polyurethane but I have not bought the acrylic paint, that is another test that I need to do.
I will keep you informed regarding those tests.
There is a long thread in the Kit building forum regarding the SE5a build, I have posted some advances of my building there.
Thanks.
