After struggling to get Poly to stick to fiberglass bows, I have begun using the Massey Finish. I have been mixing it somewhere between 6:1 and 20:1 (eyeballing it here folks...) with 2-part delayed set epoxy (60 min, I think).
It goes on nice and seems tough (2 coats so far).
But, it appears that the epoxy can be easily removed by the acetone. I found this out the hard way in a small area.
Anyone else experience removal of Massey Finish with Acetone?
Am I reallyadding additional layers with subsequent applications?
Should I be more precise with the ratio?
Thanks,
Brett
I don't think it matters too much but most folks use 1 epoxy to 5 or maybe up to 10 parts acetone or M.E.K..
If you get it up to 1 to 20 mixture it would not put much on with one pass.
I have never tried to take any off after it dried so don't know but suspect acetone would put the hurt on most finishes.

I use the 2-ton epoxy on arrows--great stuff. Put one syringe of epoxy in a baby-food jar, stir it up, add a little acetone, stir again, fill the jar with acetone, stir again.

It seems to be putting on thick enough layers, and I don't see a problem so far (it filled the grain nicely).
Oh well...we'll see.
Anyone else with thoughts? Seen Acetone remove Massey finish?
I've never had acetone remove the epoxy and I've done a couple hundred knives with it. I've only used the Devcon 2 ton epoxy from walmart. It takes 12- 24 hours between coats.
I suspect your problem is the type of epoxy your using. Chad
I'd go towards the 6:1 ratio. Wipe it on in 1 pass, don't try to rewipe to smooth brush or rag marks. Let it CURE for 8 hours. It may be dry right away but epoxy takes time to cure. Heat helps. Do at least 5 coats.
Like John said, don't thin it down so much and let it CURE. It does sound like you have a problem with the epoxy though... that stuff does have a shelf life and when it goes bad it'll never cure.
Thanks, guys.
I'm not sure of the brand, but I just ran out (3 coats so far).
Seems pretty thick. I think I have enough on for my liking. I'm going to add 1-2 coats of Poly to kill the shine. As annoying asthat shine is, I really like the "wet look" and clarity of the wood underneath.
Thanks again,
Brett
Give it a couple weeks before you put poly on it.
A couple weeks?
Well...I guess I should have looked at this site after I got home last night...
The up-shot is that this is an "experimental" bow in many ways!
Thanks!
