How does rust being porous make rust very damaging and expensive?
If rust is porous that means that water can pass through it. This means that when the surface of a metal rusts it 'exposes' fresh metal underneath to water, meaning that that rusts too.In short, rust being porous means that all the metal is effected not just the surface. When Aluminium rusts it forms a hermetic (waterproof) layer which actually prevents further damage. That is why aluminum does not have to be as heavily protected as iron (which should be painted or galvanised to waterproof it)

How old can the pool be and still get an acid wash?
Age doesn't really matter, as long as the pool is gunite or concrete. But never acid wash a fiberglass pool, or a fiberglass lining in a gunite or concrete pool. I suppose I should explain why, because so few pool pro's understand fiberglass, you will probably receive considerable conflicting information. The finish coat on all fiberglass pools manufactured in a factory is swimming pool gel coat. Unfortunately, this is not true of all fiberglass linings in gunite and concrete pools, although it should be. Gel coat is non-porous which is why it's such a fantastic finish, at least for the first 18-20 years, after which it becomes porous and must be removed and replaced. Using muriatic acid on non-porous gel coat will cause it to become porous, at which time it becomes worthless, and must be removed then replaced with new gel coat. Once it's replaced, you're good for another 18-20 years, unless muriatic acid is again used. -Bill
