After three top coats and a day of fine buffing , we are ready to ship.Very hard to get a decent photo due to glare so below are some pics of the next two bartops in line and some natural edge trim going to another job.The bartops are White oak and the trim is Ponderosa pine. We use the lifts to hold while spraying, move to a drying area, then scoop up another set for finishing. Cheers  Rob

Does the walnut lose it 's chocolate color over time and get lighter?  I've seen that before especially in a house where the wood was exposed to sunlight.  Will any of the top coats stop it?   Does the epoxy yellow over time?
Anything someone can design, I can sure figure out how to fix!
If I say it\\\\\\\'s going to take so long, multiply that by at least 3!

Brad, I don't have enough years experience to comment on the walnut losing color.Yes , generally epoxy will yellow in sunlight over time, depending. Yes there are top coats that will lessen or prevent sun caused deterioration.On this top we used AwlCraft 2000 to protect it as well as provide the best finish possible.  Rob

It does not matter the wood species, type of finish, nor whether it is ever exposed to direct sunlight.
 

 
Here is a table top in our "sunroom" that never sees direct sunlight, only some ambient.  The center always has a centerpiece and the ring is obvious where the uncovered wood/finish has lightened during the past ~10 years.  The picture makes the center portion much redder than it actually is.  Now the question is whether the uncovered portion lightened or the covered portion darkened??

Brad, I can tell you without doubt that walnut gets lighter with exposure to UV.  Under the same conditions cherry gets darker and a much richer color.  A lot of tropical woods go brown as does osage orange.  Dad was a woodworker and made walnut clocks...some were exposed to sunlight and others were in dark rooms.  That is my source of experience.

The last few years I've been using a lot of SW cab acrylic lacquer.  A couple of reasons.  It goes on crystal clear and does not yellow over time.  It also has UV absorber in it.  I've used it on osage orange, purple heart, bloodwood, and some other samples to test.  One sample is exposed to light while the other is in a envelope.  Only been a couple of years but it seems to slow the color change.  I think with enough time/UV the change is inevitable no matter what is used.

well,,,, a parting pic from today, and I hope the final picture....The customer kicked this table back  to us two  weeks before Christmas and we have been wet sanding/polishing/ buffing since that day. The customer detected small imperfections in the finish and asked me to correct all to a  perfect finish.This has not been an easy or inexpensive thing to accomplish. Supposedly this UV resistant coating I am using here will withstand the test of time given the level of work in this piece. I have spent a GREAT deal of time and money trying to find the best coatings possible in the last year or two. Not an easy or inexpensive venture - we shall see .

When you say imperfections, are they tiny air bubbles or waves or ?  Seems like getting "perfection" in a wood finish would be an impossible task, especially after as much fastidious work as you guys have invested in it.

Wow...*DanG customers!  :-\

Getting a "perfect" finish on a large table/slab is a dance of technique, patience and air quality control.

Outgassing of the wood also causes constant pin holes until you have it sealed. I've discovered that multiple, if not many, seal coats are necessary on a slab PRIOR to putting on a finish coat. ALL pinholes must be sealed first.

Having end-grain up on a semi ring-porous species would seem like a REAL difficult task in controlling the outgassing during finish. Have you tried spraying a fast-drying seal coat like shellac (both sides) prior to beginning your finish?

I'm not at expert on this, by any means...just spitballing with some things I've experienced.  8)

Oh, by the way...what a labor of love! Cool table.
Are you able to share hours invested and/or what a table like that fetches on the retail market?
I'm supposing if you actually got paid for the hours invested in would be an astounding cost!  :o
Nice work!

The way I gey my best finishes is sanding sealer or cheap varnish.
I use the cheap stuff for the first 3-4 coats Then the good stuff for
the last coats. There is a big difference in price between the good
stuff and the cheap stuff.

I had a customer one time that wanted a super high gloss white conference table 12' long 6' wide. It was made out of corian. We spent more money on the stupid table than we made on the entire job. I hate high gloss finishes for that reason.
I knew what I thought I meant.

I don't know what the customer is getting for this piece on his resale end, but I do know we spent 6 months and in the end out of pocket about 2500$. Sometimes you get the peanut-sometimes you end up with the shell :D :D :D
