Epoxy on wood?

Hi all, Am starting the latest "project", its a custom horse drawn wagon similar to the Budweiser wagon. It was built in the 80's and the owner says it time to repaint and replace some of the moulding that has absorbrd water and paint has flaked off. The wagon was painted what looks like Single stage originally and is in very good shape. Heres the plan: remove existing bad moulding, replace with PVC type( and backcaulk), sand all panels, fill any dents, chips with JB epoxy, sand as needed. There will be bare wood on some edges etc, so I think using epoxy all the way thru would be best,( stays flexible on wood) probably 3 sessions, sanding as needed between coats, seal w/ epoxy, spray 2-3 coats single stage or basecoat color, then clear with UV. Most of the panels are MDO plywood, (exterior sign painters board) Probably will use either deltron or omni single stage, or omni basecoat. So, anyone done it this way?? Whatcha think about this process?? Thanks, C
 
I'm not a wood person but deal with a lot of people that are and my take would be this.

Forget the epoxy JB stuff.
Shoot a coat of epoxy and walk away for a few hours so it sets.
Then spray a second coat, this will stop the soaking.
Next day apply a 2 part glaze over the epoxy for minor filling.
 
Bondo is used as an exterior wood filler for nail/screw holes and repairs on homes, so like Barry said the glaze would be a good choice.
 
Thanks Bary & C10, Sounds good! I do question using glaze/bondo type products, in my former life being a carpenter/builder for 35 years, I have used different types of bondos, and with the natural expansion and wicking moisture of wood, I've found that the talc in the bondos will fatten and puff out a little, instead of the JB I may go with duraglass, with the resin in it. Thanks again!

You are right and that is why the filler is applied over epoxy to prevent that problem, the epoxy will act as a barrier coat and give the filler flex and strength.
 
Reviving an old thread here, but exactly what I am curious about. My 1949 3800 Chevy flatbed will be getting a brand new wood stakebed built once I am finished with the truck resto. I initially was going to rebuild with oak. However, the few estimates that I had received were way out of my budget. It was originally built with yellow pine, and lasted from 1949 till now under hard work and little care. I'm just trying to determine what will be the best thing to lay down to protect it and thought about SPI epoxy. The bed will be black. Thanks
 
We clear and epoxy over pine beds a lot, just make sure wood is dry and it will work fine, pine has its potential issues but I have never heard of a problem, with either product as time passes and some of these projects were just plane abused with the way they were painted.
