WOW it had been 4 months since I worked on the plane. The house is eating me up in time. The weather has been so nice that the house jobs have taken priority. I stripped down the doors and got ready for primer. I tried Stewarts water born high build primer and found that the sanding was not powder and sticky. I then tried Lordco primer with an additive and had good adhesion and sanding properties. I still have the shower to finish in the house and will get back into building full time soon ( after work that is ).
