I bought a used boat with chalking. What worked for me was 500 grit wet/dry
paper - 1200 wet/dry paper and then used a polisher with a wool bonnet which
can be purchased here --

you cannot find a better deal than this price on a polisher. It has a speed
adjuster perfect for buffing out the last of the chalk off your gelcoat. I
used SEA BOWLD LIQUID RUBBING COMPOUND -for medium oxidation, and SEABOWLD
SUPER SILICONE MARINE POLISH. I applied the polish by hand and removed by
hand. It was less work than I thought it would be, but it does take some
time. Also- I did not try to remove stains in the gelcoat from oil/grease,
cause I probably would have to go too deep into the gelcoat. When it was
polished it is barely noticeable.
First completely wash the boat with - carwash (that is what I used)
Second get a bucket with soapy water and wet sand the chalkiest area with
500 paper
Third go over again wet sand with 1200 paper. This paper wears out fast so
buy enough like 20 sheets. I bought packs of 20 sheets each of 500 1200.
(I used a sponge with the paper to even out the presure while wet sanding.
One of the green and yellow 3M SCOTCH BRITE pads, the paper folds around the
sponge perfect 3 times. When the paper wears out, use other 1/3 of paper ).
ONLY USE THE SAND PAPER ON THE CHALK ! USE THE POLISHING WHEEL, AND RUBBING
COMPOUND ON THE SHINEY GELCOAT.
USE LIGHT PRESURE ON THE SAND PAPER, ONLY TAKE OFF AS MUCH WITH THE SANDING,
AND LET THE POLISHING WHEEL DO THE FINISH WORK.
Be careful around sharp edges of the boat where the sanding would remove
more of the gelcoat and go through the color.

Sorry if this topic has been covered before as I am new to the
internet and boating in general.
I recently purchased a 24' boat that has what I assume is chalking of
the gel coat from exposure to the sunlight.
I did a google search for a way to remove the chalking and it seems
that a thorough use of rubbing compound is the recommended way.
Just wondering if there was an easier way as I don't get very much
time off from work and would like to spend that little time enjoying
my boat on the water.
Thanks in advance
