The first, and easier to treat, stage is less advanced. If the gelcoat returns to normal when it’s hydrated (or just wet), then you can treat it using the same chemical solution as the less sever case mentioned above. However, it will take up to 6 months for the treatment to totally dissolve the calcium chloride. Due to the time this takes, and the fact that the water will be very acidic in this time, we recommend that this treatment be done in the off season. If, perchance, the salt deposits are visible even when they’re hydrated, the treatment is not as easy. An effective chemical treatment hasn’t been found or developed so the recommended solution is to remove the salt is to buff and polish the surface to return it to its previous condition."
Your manufacturer is full of it. Calcium chloride is an EXTREMELY soluble material: at pool temperatures you can dissolve a cup of granular calcium chloride (sold in the pool trade as "calcium increaser) in a cup of water! There is no possible way it could coat your pool.

I don't know whether your manufacturer's tech guys are dishonest, or simply really, really ignorant.

Can you email me (poolforum@gmail.com) the specifics of your problem . . . and a link to the tech bulletin? Meanwhile, I'm going to as Waterbear (who has some knowledge of fiberglass) and Chem_Geek (who knows chemistry) to take a look.

Sorry for your bad luck!
