Finally had good weather today and had a chance to prime the tips. Made a final pass with 400 grit and filled a couple pin holes.
Then mixed a total of about 300g of EcoPoxy. Thinned with 20% water and shot through a 1.3mm tip with about 12 psi at the gun. Came out great. Smooth satin finish. A little dust in the finish so not perfectly smooth but that what I get with no paint booth. Acceptable for primer.
So glad to have it done as I can clear out all of the epoxy, filler and sanding devices from the garage and have more room for the growing fuselage.
