My plane has been in Smooth Prime primer for several years now and shows absolutely no ill effect. I discussed this with the manufacturer and they stated that "a freshly coated plane in smooth prime MUST be allowed to cure in low humidity for a minimum of three (3) weeks. The same goes for a plane which has been primed for a long period of time to allow for any absorbed moisture to dry out." Now, I have applied additional coats of Smooth Prime to my plane after the first coats were months, maybe years old and have no ill effect. I agree that oil and fuel will soak in and cause problems. If that happens, simply sand that area off, re-prime it, then paint it. Of course you must do as the manufacturer says and allow the primer to cure in low humidity for three weeks before priming. That is, if you want to do it right. Man, some of you guys want to beat a dead horse to death again and again. Let's move on to more constructive building techniques. I think everyone knows not to fly a plane in primer forever. But of course you could...... Winter storm here this weekend, blizzard conditions with up to 40mph winds and an additional 10 to 12 inches of snow. Some day, I will get to fly my plane.
