I haven't talked to them yet as I thought the first flaking was where a tape should have been. The complete failure was noticed yesterday.I haven't seen any peeling issues with Stewarts top coat. Have seeen the bubbling and orange peel. What did Stewarts say about the peeling when you discussed it with them?
At this point I see no reason to. I followed the instructions and the video. Everything looked perfect for almost three years. There seems to be an equal number of people that had the system work vs. people that had to redo it a few times for it to be just acceptable. Very few that did it years ago to be able to gauge durability. A couple of months ago I would have been one of the people praising it. Now I'm just looking for a way out.
A better question is why are so many people having problems? We keep hearing that "it's waterborne, it shoots different". Well, so was the glue and Ekofill and I don't see people having problems with them. Maybe there is a problem with solvent entrapment. Maybe the problem is actually the Ekofill. One things for sure, applying a urethane topcoat is the worst place to be having problems. What help is calling the manufacturer, years after following the instructions, for some things to "try", that may increase the odds of success from 50% to maybe 60%? It all starts with "cut the old fabric off...". Maybe I'll get four years next time before I have to spend time and money to do it over again. Believe it or not, I'd rather fly my plane than redoing the covering three or four times to get it right. The system is ruined by an extremely difficult topcoat. The Stewarts need to open up the STC to other topcoats until they can fix theirs. Singing the praises of Ekopoly to people that have had multiple failures with only this particular paint is not good.
My original question asked if anyone tried a different topcoat. To switch to a more proven system I'd have to strip all the parts that are now sitting in Ekofill anyway. Only makes sense to try a different paint and see if it sticks. Short of it having a bad reaction with the Ekofill, I can't see any problems and the durability can't be any worse.
