A claybar will remove the dirt left behind after washing the boat, this will
eliminate future swirl marks by removing the grit that will cause swirl
marks on the fiberglass.

The only way to remove the swirl marks in gel coat is to polish them out.

JimH did provide excellent guidelines, but I would be very careful when
using the random orbit polisher. If you keep the OP in the same place too
long or you push too hard when using it. can burn the gellcoat.

My fibreglass boat while it shines, if you look at it at a certain
angle,
you can see swirls . and this bothers me. Has any one had an experience
like
this and what product would you recommend to remove the swirls or the
wax
from a fibreglass surface?

Sometimes the swirls aren't in the wax, but in the gel-coat.

Using diswasher detergent (Dawn brand works good), remove the wax from a
portion of the finish and observe whether the swirl marks remain. If
they do, you'll probably need to claybar (hard work) the finish to remove
the swirls. Check with an autobody shop.




The swirls are indeed in the gelcoat itself and need to be polished out.
No need for a claybar. Follow the steps I previously posted and it will
come out looking like new. An investment in a random orbit polisher is
needed, as well as the use of the proper products and polishing pads.
