for you guys that have used helmsman spray poly, how long does it usually take for it to cure. i used it for the first time yesterday and it is still really tacty (wet) today. i read on the can that it take 72 hours before you can sand it but i thought it would have been farther along in the curing process than it is. so how long and is there any thing that i can do to help speed up the process.
That's 72 hrs for re-coat. What type wood did you spray it on? Normally dry over night. I can usually handle a bow after 3 hrs and buff out and apply a grip the next day. But a lot depends of the temps/humidity......Art
on a glass bow with a coco riser it hasnt dried on much on any of it
It won't dry on coco, but should on the glass.
You will have to seal the coco with CA or something to get it to dry.
The times I tried it, it would pretty well dry 1st coat on coco, but when you spray the 2nd coat on, it turns to gummy yuk!
I tried automotive clearcoat on my last oily wood riser, then buff with steel wool for satin finish. (this came from a fulltime bowyer!)
Rattlecan from O'reillys Auto parts. Not sure on durability? :dunno:
so what do u think i should do, so i give it more time and see if its going to cure or just start stripping it now.
and if i need to strip it what should i use.
kenny my bother saw the coco lams we got from you and he loves em. thanks for everything

Might as well strip it now. It will never dry. Seal the cocabola with several coats of superglue. sand smooth with 320 or 400 wd and recoat with a thin coat over the entire riser. Then spray a light coat and see if it sets up. You just have to keep doing it until it sets up. The higher figured and oiler the coca is the harder it is to seal it but its worth it to do it.
God bless you and good luck, Steve
Just use Krylon crystal clear acrylic on everything. It's easy to get and dries on everything. No need to seal first. there are mnore durable finishes out there, but if it gets scratched or dinged it's easy to fix. You can use gloss flat or satin, it's good for exterior as well.
Mike, I've heard that also, do you use it on any?
And how waterproof is it?
Thanks!
after talking to kenny last night i went ahead and stripped it and went and got some auto clearcoat. i sprayed the first coat last night and it seems to be setting up good.
thnaks for all the help, this was not a fun lession to learn the hard way
You can also use Shellac as a sanding sealer then coat the Shellac with almost anything.
I've had good results using the Massey epoxy wipe-on, 6 or 7 coats, 0000 steel wool between coats until all the grain is filled; then I spray a final coat or 2 of deft or poly satin to cut the gloss. Makes a very tough finish but is also glare free and easy to touch up. I like the Massey because it dries quickly. I usually recoat once a day, but in warm weather you could probably recoat in the evening from a morning coat. I had no trouble sealing cocobolo with this method and the spray-on dried well in 2 days.
Kenny, it's pretty much all I use now. Mostly because when a bow gets scratched or something the customer can find purchase easily and fix it, with out too much trouble.
Thanks Mike! Good info guys!!
I used the krylon crystal on a browning cobra refinish and it turned out excellent.
