Double Gloss Coats???

All the top new longboards I see gotta have double gloss coats, don’t they? How else can the “big boys” get such a great poly resin depth?

Depth, they can just add a layer of 4oz over the lam, then hot and gloss as normal.

So, doing a 6oz bottom and a 6/6 deck, just add a 4oz right over your first lam on each? Might bring things too heavy. How about a 4oz bottom then another 4oz on top of that? Deck a 6/4?? Instead of laying down the 6/4 together (traditional) you do them separate??? So you just go ahead and lam as usual? How much weight does it add?

kinda sorta if you’re looking for depth of gloss, and 3D effect, any weight gain is not important enough to worry about.

weight, do a polished sand coat, double 4 deck and single 4 bottom.

What exactly do you want?

Longboard with pristine showroom shine and resin depth. Obviously, glassing with the usual 6 bottom and 6/6 deck and then slapping another 4oz on each side will cause too much weight. I’m just suggesting using double 4’s on the bottom and then a 6 and a 4 on the deck. Approx original glassing weights. What do you think?

add the extra layer of 4-oz with a tight freelap, then hotcoat, and sand all the way down to the weave. gloss and polish as normal.

Thank you 220 for your posts about gloss resin.

I’ve had some great successes and failures with gloss. The input from Swaylocks has kept me gloss coating. I have several ideas and techniques that I’m exploring and threads like this keep me going. In the car business we would sometimes clear coat and then sand with 400 or 600 and then clear coat agian. This would give us the depth we wanted in the finish. One problem I am currently having is keeping the finish flat. I’m trying different sanding methods and different sanding blocks and pads and working with paper grits like mentioned in your other thread. I have no desire to add an extra layer of 4 oz to get gloss depth. No offense anyone.

No air movement, More catalyst than ever imagined. Special mixes. All in the archives.


I couldn’t find much on this subject in the archieves. So, do you double gloss coat? Does it work? Thanks.


There is another way. I’ve had excellent results with a double hotcoat that is then sanded by machine, then block sanded down through 100, 150, 220, 320 grit paper, and then glossed and polished. The effect of the double hotcoat is that there is very little, if any, cloth cut in the sanding process, there is good resin depth and good visability to the foam surface. Boards finished this way have always seemed to have more “depth” to the finish, more light reflected back to the viewer. Possibly this is due to the hotcoat resin being a little more clear than the glossing resin.

There was a post a while back asking about Cooperfish Gloss technique. The question was the same, do you double gloss to get a deep 3D look.

The answer was no.

Like mentioned before. After lamnating. They would then add another layer of 4oz top and bottom and tthen hotcaot and glass as normal. the extra layers of 4oz would add the depth that you a re looking for.

BUT, to answer your question:

doing a double gloss coat doesn’t add anything to give a deeper look. The layer is so thin anyway how could it.

Proper glossing, sanding , polishing will give you a showroom quality finish regardless of the extra layer.

if my memory serves, gene listed the primary reason for the extra 4-oz and sanding through the hotcoat into the weave was to minimize the amount of un-reinforced resin, thereby giving the board a better strength-to-weight ratio. with nice, clear glass, you’ll get that added depth…but there’s no substitute for a good gloss & polish technique to really bring out that showroom shine.

…but in the bottom youve got 2 layers: the lam and the lap…and when you finish the board, you dont see the 3 D effect…so…

Also, keep in mind that having a thick layers (multiple hotcoats, glosscoats etc.) of resin without reinforcement on the board can lead to stress cracks, especially on the bottom of the board. I think that the way Cooper does it (extra layer of 4oz) is the way to go. -Carl

And 4 oz hot coats so much cleaner because of the finer weave. You’ll then hit less weave when sanding aqnd get some strength for your weight.

Bills right too. We used to do a lot finer sanding when gloss/rub out was really looked at closely. Today I see glosses with big puddles, brush marks and streaks. The laps aren’t fair especially in the nose and tail and the rubout guys waffle almost every board. All stuff that would have been unaccepable in another era.
