Dulux Weathershield is good. So are most of the oil based exterior glosses from almost anywhere.

Rub it down gently and then wipe over with panel wipe to ensure no contaminants. 

 

If the Matt comes off on your cloth when using the panel wipe then you’ll need to go back to bare metal and prime then undercoat.

Check that the 'Matt' finish is not Bitumen. Wipe over a test patch with a cloth, wet with white spirit, if it comes off it will be Bitumen, and will not take any paint unless it is all removed.

If you use your boat then that's a high wear area, some of the paint will get scraped off, and when you repair it the edges of the scrape will show through. A matt or silk is much more forgiving of this sort of thing.

I painted my gunnels with Black Gloss Toplac in 2015. Just had 3 weeks out of the water and did them again. Rubbed down the Toplac, undercoated with 2 coats of Craftmaster High Build Undercoat, topcoated with 2 coats of Craftmaster Graphite Grey Raddle. I would always put a couple of coats of undercoat on, even if the fundamental colour isn't changing.

Painting it with the same blacking as the rest of your hull is the lowest maintenance option.

Thats how mine was when we got the boat and I found the opposite. Constant touching up requires keeping a pot of blacking which is nasty messy stuff and brush cleaning is a fag. The new and old do not blend in well. Also some/many blackings do not keep well once opened. A "slap it on" silk black enamel is my choice. I have used the Andy Russel Gunwale paint for a few years now, it goes on quickly and dries almost instantly. Its harder to get now so I might get some direct from the maker if I can, but am also tempted to use Craftmaster black high build undercoat instead. Craftmaster high build undercoat is lovely stuff to use.

Sit in the cratch and watch 20 to 50 boats go by and decide whether to go gloss or blacking or matt.

 

Personally I would never do gloss. 

 

Glossing below the gunnel appears a modern fad.

Painted some of my old boat with Dulux Weathershieild,but it is now waterbased,

The Dulux  decorator centre didn't have any of the old oil based stuff.

I was a bit doubtful about the water based Weathershield,however,it went on easily,dried very quickly (too quickly really on a warm day) and has been on for eighteen months now, and still looks ok.I used the satin finish paint.

I would agree with those who suggest avoiding full gloss paint, it shows every ding and scrape. I use a "direct to metal" anti-corrosion semi-gloss or semi-mat depending on your point of view from Toolstation. Apply at least two coats as per the instructions and it looks fine without highlighting every bit of damage.

I slapped some Zinsser all coat exterior black on our gunwales last year. Went on easily, covered well, looks good. From Screwfix. Supposed to be satin but it's fairly glossy.

Personally I would ensure that every horizontal surface on the boat that has the slightest chance of being stepped upon is painted with non-slip paint of whatever kind.  This after broken ribs after stepping onto someone else's boat and falling on a cleat.

Your local Dulux Decorator Centre is wrong, Oil based Dulux Weather Shield is still available, and is advertised on their website, although it appears to be only available from them as a "Trade Paint" these days. Personally I never use the Dulux Decorator centre, preferring to get my gloss Oil based Weather Shield mixed by our local branch of Brewers, they do not appear to have any branches near you, but any good paint trade merchant should be able to help.

I agree with DS. Oil based is still available.

I painted our garage door with it and what I used was definitely oil based.

Notwithstanding this, there are some excellent water based paints around these days. One I used a while back was so good I didn't realise it was water based until I tried to clean the brush in white spirit and it would not dissolve the paint on the brush. Most confusing!!

 

Sadly I can't remember what paint it was tho....

I agree that there are some water based paints which are high gloss and durable, but you won't buy them in a tin from B&Q.
