X I M primer was about about like a thin layer of paintable polyurethane adhesive and is more expensive.

5200 seems to fill small deep cuts better. The wet faired 5200 fills look the best.

I guess it's a propane torch and plastic brazing rod for the keels again. I have done this so many times I am beginning to wonder how much keel I have removed.

Since I do this free hand with a propane torch and a putty knife, if they come looking like a NACA foil, thats ok right?
