The term Hard-Shelling (circa 1980) - is the practice of covering foam with micro slurry, letting it cure, sanding it and then applying a fiberglass layup over the top. (not recommended)
..................................................... Hi Larry C - can you say a bit more here. This is precisely the mistake I would make (working alone). Not unlike Larry F my rationale would be to avoid rushing and do it in two steps - I would happily believe that I was going to achieve BETTER results by taking my time. Is this not similar to a second lay-up (over a cured lay-up) with whatever precautions would apply, like peel ply or sanding? In this particular case I would have thought that the adhesion of the subsequent cloth /resin to the layer of cured micro, however low, would be substantially better that then mechanic strength of the core material. i.e. - no matter how it was done, the bond (and shallow penetration zone) between micro and foam would always be the weakest link.
