As we were discussing in another topic, what we have been using here in Alhandra, Portugal to paint our hulls (lots of UVs all year 'round) with great results is two component Polyurethane.

The key to a good paint job is always surface preparation and we DIYers usually go like this:

1- Removal of the old paint;
2- Surface repairs with epoxy
4- Surface rough smoothing
5- Degreasing (celulosic thinner, acetone, MEK, etc...)
6- 1 coat of epoxy primer
7- Surface smoothing with filler
8- Light/medium sanding (120 grit)
9- Degreasing (celulosic thinner, acetone, MEK, etc...)
10- 2nd coat of epoxy primer
11- Light sanding (Scotch Brite or 240 grit)
12- Degreasing (celulosic thinner, acetone, MEK, etc...)
13- 2 coats of polyurethane sprayed or rolled top coat. We usually apply the 2nd coat as soon as the first one starts to set (about 2 to 3 hours later) thus eliminating the need of sanding between top coats, which would remove precious paint...
14- Let dry and harden for a couple of days and wet paper sand and polish if required

On the deck we also use polyurethane 2 comp but we do our own anti skid, like this:

1- As above
2- As above
3- As above
4- As above
5- As above
6- As above
7- As above
8- As above
9- As above
10- As above
11- As above
12- As above
13- 1 coat of polyurethane top coat
14- Abundantly spread thin sand over the paint surfaces where you want to apply the anti skid treatment before the paint starts to set. We normally use UNUSED sand blasting clear white sand.
15- Let dry
16- Brush or blow away the excess sand
17- 2nd coat polyurethate top coat

You can regulate the "harshness" of your anti-skid either by applying extra coats of paint or by using thinner sand...

Regards!

11- Blow away all the sand
