[C320-list] Bottom painting

[Jeff Hare]

Hi Mike,

Nearly all bottom paints (except barrier paints) are Anti-fouling.  There are hard paints and ablative (soft paints that wear off) paints. 
Your diver should be able to tell which of the two kinds you have.  Ablatives need to be reapplied when they're worn off and lose their effectiveness,  hard paints need to be reapplied when either they lose their effectiveness or start chipping off.

Read the West Marine articles on their website on bottom paint to better understand this. 

That's really all the advise I can offer. 

Cheers!
Jeff

Thanks for the responses so far. As I mentioned earlier, my diver  
lists my bottom paint condition as  "Good: 85%-70% Anti-Fouling." At  
what point should I have it repainted?

Thanks,
