Actually, over time, the wax tends to remove itself leaving behind
deposits of dirt and encrusted grime. The problem with using any kind
of stripper is that it's going to leave a residue itself and if not
done properly, can FUBAR the paint job.
I've seen this done on hulls that don't need a lot of repair, but are
going to be repainted and it's time consuming, but simple - namely wet
sanding with 120 grit sand paper. Depending on how big the boat is, a
couple of rolls, an orbital sander and a day or so should take care of
it if your boat isn't more than 25 feet or so. Two days at the max if
it's a little larger.
It's the only real way to strip all the left over crap from years of
waxing. It's not any more work than using a stripper either.
I did this on my first Contender which had sat for a while and
garnered a ton of dirt on the hull. Worked great, only took a day for
32' of boat and believe it or not, the shine is still there after a
couple of years - I've only washed the hull every month or so.
