It's not that bad.. first the top layer chunks off into big pieces then you hit the core of the glue and thats when the "uniform" surface starts to show between the glue and plastic. It only takes some time because there's so many seams to be filled in on the aircraft. (I put glue over every seam, just as a safety valve). But its been the best path for me, as putty shrinks and sinks, CA does the job!
