anyone used artists oil paint on foam then glassed over in polyester?
found this
"Not sure what you’re calling “polymer resin” unless it’s the Part A to the Part B of MEKP that make up a “polyester resin.”
If so, you can buy special colorants to use with resins, or you can add
your own colorants but not every colorant is compatible with resin. One
that is is artists’ oil paints, the kind of oil paint that comes in
tubes at craft and art supply stores (though the artists’ versions of
acrylic paints also come in tubes, but they can’t be used).
Those oil paints are translucent though so the tinted resin will be
too… if you want an opaque color you’ll have to buy the opaque
colorants for resin or add some white paint to any color you mix (white
is always opaque).
You could perhaps use powdered pigments or other powders too.
(If you mix a colorant that contains water into a resin–like acrylic or
latex paint for example-- it will cause bubbling or later cloudiness
and maybe other problems since resin isn’t water-based.)
I know nothing about repairing fiberglass pools though. You’d be better
off asking that in a group that deals with pools, or perhaps a group
that deals with making various things (surfboards, costumes, etc) from
polyester resin and fiberglass cloth. You could also perhaps ask at a
local pool supply store, and they may even have repair kits or"
no one figured this one out yet?
mybe no one is interested? wot about cutting a deck plug with a razor blade.

hiya paul !
ummmm....
.....where did this info come from , i wonder ?
when whoever wrote this said "oil paints " ...
do they mean acrylic or enamel ?
i ask , because i had problems once .....when i sprayed a blank with enamel paint , and then glassed it
i encountered no such problem with acrylic paint when i sprayed a blank with it , then glassed it ....which seems to be the opposite of what this person is saying ....
i have also used artist tube acrylic [like you buy in newsagents ] as a cheaper option to tint , and pigment , in fin panels ....it was fine ....i can't comment on using it on foam though , as in tinting a whole board .....
okay , mate , I hope this helps ??
cheers !

hello there
hi ben. the colours are far better then even the best quality acrylics. yes the board would be handpainted like a canvas by a prominent artist then glassed. looking at a around 2 to 3k for a shortboard. also i like the idea of mixing it with the resin. the problem with acrylics is that you can only really get good colour from the tube and they look muddy if you mix them. we are doing an experiment this week both under glass and as a tint. just thought all these creative people may have tried it
hi huie what do you mean with the deck plug
no it would be oil paint from a tube that artists use
also i had another idea about replacing fins with nodes or shaped lumps
like a really short fin thats really fat
Artist oil paints take a long time to completely dry/cure. The linseed oil binder in the paint dries by oxidization, not evaporation like water based paints. That could actually take weeks to totally cure.
You probably will have to seal the art with something that will help the resin bind to it. I have no idea what that would be.
Read the part on oxidization at the bottom of the linked page:

best bet might be to do the oil painting, take a good digital photo of it, and then have it printed on a high quality printer in a format that can be laminated (rice paper or fabric). There is a guy who advertises on here with a service like that, can’t recall the name (Marlee?) but you can look for posts in the industry section or surfshop.
I guess my first question is whether this board is meant as art or are you going to ride it? Assuming it is art I may be able to help. I worked on a board that was painted by a well known artist. It was used as an art object and not ridden.
This board was painted using oil paints on a sanded hotcoat. We let it dry for 30 days and sprayed a coat of clear acrylic over the art work. I let this dry for 24 hours and lightly scuffed it with a scotchbrite pad.
Next up I glassed over the art with one layer of 4oz glass. it was then (again) hotcoated,sanded,glossed and polished. The 4oz glass overlay gave it a super smooth surface and it polished out great. This was what we were after.
Actually the board looked pretty good with just the acrylic spray but it was too flat and looked more like a backyard paint job.
This was all done on the deck. It is hanging in an art collectors gallery.
In a nutshell…if you let the oil paint dry and spray a coat of clear acrylic it may work. I am not sure about doing it on the foam.You could run in to delam problems if the board is actually ridden. Hope that helped.
(As an afterthougth i have been seeing more boards treated as art objects.The outline and flow of a shaped board is thing of beauty. I realize Swaylocks is about boards made to be ridden, but you can take it to another level. Kind of like custom cars…made to be admired and not driven to the Mall. I bet Jim Phillip’s amazing sunburst board bought by Rusty Priestndorfer is just that. A thing of beauty made to be preserved.)
thanks for that link atomized. possibly some sort of acrylic fixative . although if the paint was thin on the foam ? who knows.
hi Kieth . im going for more a one off idea
hi cleanlines thanks for your input dude. yeah you have exactly what i got in mind . not neccesarily intended to ridden, but able to. it would be worth alot as art and i guess if the customer had money to burn then they could surf it
here i did some searching and i think these two guys are onto something
Chip – (with all due respect) Oil, as in paint thinner, not acrylic, as in water clean up.
Yes. It would have to be done on the foam to have some texture for the glass to bond to if someone had any hope of riding it. If it was done on a sanded hot coat, I see many headaches in someone’s future. That would be more of a paint pen process, just much more drying time, then a better and thicker sealing process.
I have given this some though as I have done some seascape oil paintings.
We’ll see. Maybe more info in the future, or maybe not. [evil grin]
i think that any paint oil or acrylic, put on thickly would be a problem . however thin applications of paint would be ok. I cant see a problem with it but ill let you all know how it goes. i think we will go for indian ink and oils on foam
Howzit Paul, Inia ink is great for art work on boards and I got to the place where I used it a lot for pinlines and small art but not for painting like a whole board since it can get very expensive when using large amount but for pin lines nothing is better except pigment. I think that oil based paints are going to cause major headaches when you go to glass over it. Aloha,Kokua
