I want to refinish my jet ski hull. What is the best way to do this?

Question

I am thinking that the best way is an epoxy finish but I have no idea what product to buy and the process of doing it. (Do I need to fill scratches with marine putty and sand? etc.) Looking for input. Thanks.

Answer 1

poo on it then smear it in

Answer 2

The best way is to fill the scratches, sand it and spray a new layer of gelcote.

You can also try first to get a gelcote repair kit, sand only in the scratches (not around), mix the gel cote with pigment to get the right color, fill the sanded and de-greased scratches, then wet sand 800 grid and buff/polish the hull of the ski with marine rub compound (3m).

Depends on the finish you want to get...

For a tough finish use epoxy with a 200gm sheath which will obliterate all imperfections add strenght but also a little weight, you'll also have to paint it with a two part polyeurathane as epoxy unless specified is not UV tolerant so it needs protection from sunlight.

For a smart professional finish if the sub-laminate is sound, I'd just flatten back the existing Gel-coat spray with a polyester high build primer flatten and finish with a sprayable polyester Flow-coat to the colour of your choice.

The latter is easier, takes less skill and is less labour intensive.
