Hi!

I own an old Dagger Legend, made of Royalex, that has seen a lot of rivers and rocks... so I decided to repair it, and give it a second life.

After reading about the ABS/MEK receipe, I initiated the repairs. It's going very well, and the ABS layer is almost done.

The problem is, that when I tried to create a paste with vinyl, it simply doesn't work. It begins to flake and plastic pieces just weak, but it doesn't create a mastic, like with ABS pipes.

I wanted to spray a vinyl plastic layer over the repairs, and even on all the boat, but can't seem to find anything that could do the trick... until yesterday:

Yes, I found something that may interest some of you. It is liquid vinyl plastic paint that can even be thinned with acetone. That's what I would like to use to recreate the outer vinyl layer. I would buy a white gallon this paint, and use plastic pigments to match vinyl color.

Here is a link to get paint's description :

I would like to have your feedbacks on this idea!

Sounds like a bad idea to me because of this sentence:

Please ensure that you are applying this coating on only new unpainted PVC buoys.

You're going to be applying it to ABS. There might be a problem.

I would suggest using Krylon Fusion spray paint. There's been lots written about it at this site.

I will try to get more info as if it does work also on ABS, like you said, it could be a problem.

I think what they mean is to use this liquid vinyl only on pcv-like material, with no paint. As the outer layer of Royalex canoes is vinyl and not paint, I think it could be a great alternative since acetone will recreate chemical links between the original vinyl layer and the new sprayed one.

I think this paint is a different blend of MEK, Acetone, and another composite. That's why it couldn't be dissolved with only MEK.

I'll give more feedback on my researches.

That could be interesting. Note :

* I have been using Acetone + ABS to make the paste, not MEK (at least not any more). Both work fine, but MEK seems to be the nastier chemical of the two.
* Krylon Fusion (and the comparable Rustoleum product) do protect the ABS from the sun, but, the add no abrasion resistance - they both readily leave their mark on rocks...

Course, it is all busted up again but that is after a GC run, some Numbers, a dozen Fractions, some Daddy's and whatever else.

I wuz happy with the repair.

Hi all!

I just wanted to keep you informed about my project.

I ordered the flexabar vinyl plastic paint, and I finally got it this morning. I've done two tests so far, on ABS and on PVC, and it is working very well. I dries to the touch under 30 minutes, and cures overnight.

I'm not surprised that it works also on ABS... on the manufacturer's website, I was written that it works with PVC, EVA, Polyurethane, Polyethylene and Styrofoam. While Styrofoam is only a trademark, it is made of polystyrene, just like ABS is. I don't think I'll be getting any problems.

I'll keep you in touch with it.

Looks very interesting. Please keep us all informed on how your product test works out. Looking at the picture of the can, I see this paint is either made in or distributed from a company in New Jersey.
Seems like that is were all the good chemicals come from. There should be a US source for this stuff. I'll have to do a search. Thanks for posting this up and please give an update soon. Jim

Here is a place in New England probably get it at any coastal area

Some news...

okay, I tried to pigment the white Flexabar paint to dark green without success. I didn't thought that it would be so hard to get the color from white. So next time, I will order directly from Flexabar, and will ask for the good color. I just dont know how to define the color I want ? Maybe using the pantone color matching system ?

When I looked on the site it seems the paint comes in a good but basic color selection. If you need a dark green, buy the big can of green and a smaller can of black and custom mix it. Typically most colors can be darked a shade by adding black to them. Go very conservative when adding the black. You could try a small batch and do the addition by weight if you have access to a good scale. Document your mix ratio so you can duplicate it if needed in the future. Good luck and keep us posted.

Thanks Jim, I bought the paint as fast I could, and didn't realize that I could simply mix different can... well, anyway it is done. Maybe next time.

I've done a little trip last week with my Legend and I think the repairs are great and there are no scratches on the paint... so I think Flexabar paint is great to replace the outer vinyl layer.

I hope this will help many people keeping their boat a lot longer.

Fine! Now, let get dangerous!

I forgot to tell that I applied the paint with a air spray gun. I thinned the paint a bit with acetone.

could always do a second coat W/color
