A buddy of mine recently bought a boat that had been used on the coast in salt water. The boat is now on a freshwater lake and he is looking to apply Micron CSC. Unfortunately, he doesn’t know what paint is currently is on the bottom. His mechanic said to use a sandable primer, but I’ve looked on the interlux site and am unsure about what to recommend. The boat will be sanded before the primer is applied. Any thoughts would be appreciated.

Sandable Primer
Micahel: A sandable primer is one that needs to be put down over a sanded surface for good adhesion. A "No Sand" primer achieves adhesion by chemically softening the surface over which it is applied. Sea Hawk paints says their "No Sand" Primer is good for about a year if you do not sand the surface before applying the primer. But if you sand first they say it is good for a second year.

Sandable Primer
Thank you for the info. So it seems that a “sandable” primer isn’t completely necessary and that a “no sand” primer will work just fine, once the old paint (there isn’t much left) is removed. Is there an advantage to using one verses the other since the hull will be sanded anyway? Will one last longer than the other?

I've had good luck with Interlux Primocon primer. This might be a good choice if you plan to use an Interlux product over it.
