Just an update ive had good success with this product only draw back is the sun doesnt shine very often in the winter months and its to cold to cure outside so had to order some UV cure lights and its working well , 3 quick coats, light sanding in between and ready to finish in about an hour.

I see you can buy it by gallons. Is it sprayable. Can it be used under a solvent finish like Krystal?

Have you tested this by letting it cure overnight in 80-90 degree temps?  Some of these sealers will shrink. I've never seen this one before. Do you have a MSDS sheet on it ot tech data on exactly what this stuff is? 



Never mind Bryan, i found the data sheet.....   This is polyester resin and has excellent solids for filler.
Is this the same product you purchased?  I couldn't find one that said "Grain sealer filler".

Brandon Stahl use to swear by polyester grain filler for a base for gloss finishes.

Solorez does have a few different products this is labeled as grain filler its is actually very thin and the idea is to only fill the crevices and leave very little on the surface , put it under the light or better yet in the sun and ready to sand in a few minutes i use alot of wenge and its been working well I apply it with my finger and wipe the contours of the riser with a strip of stretch wrap, (idea i got from Rob Nicoll its quite brilliant 😊 and then spray my auto clear finish.

So where do i buy some like yours? i can't seem to find it on their website... gotta link?
Wenge is tough to fill just using a lacquer base filler. i've used an epoxy / acetone slurry before, but it's a mess and needs to dry over night.

I buy it from a specialty finishing shop here hes also the Mirka dealer so i buy all my sand paper ect from him you should be able to find it ... it is made in the usa, i buy the smallest bottle a little goes a long ways i will fill a complete riser one coat with 2 finger dabs of finish .. i used a small flexible auto body plastic bondo spreader and that worked really good flexes around the contours of your riser leaving very little on the surface and fills the grain..... i did a wenge riser tonight 3 coats sanding in between with UV light to cure i was ready for finish spray in about an hour, sands real easy just like laquer.

Stic iam not really familiar with Krystal but i think once its cured and sanded i think you could top coat with most bow finishes. They do recommend applying the least amount of product only filling the grain so I don't think you'd wanna spray it.

For $53.00 a pint, i think i'll pass. :o  :o .. Glad it's working well for you. Too rich for my blood.

These UV fillers and finishes are amazing. I can have a bow from sanded and ready for a finish to shooting arrows with a fully cured 2 lays of finish in under 30 minutes. This is one I did for my son a few nights ago.

Krystal is a conversion Varnish. Very user friendly stuff, but doesn't hold up to heavy use in hunting conditions and rain as well as an epoxy finish or auto clear coating does. It was real popular years ago. I sprayed a bunch of bows with it myself, including my own hunting bow at the time. I ended up refinishing my bow in 2 years time, and decided to try the Thunderbird epoxy finish... 

That Thunderbird is tough as hell, but very expensive. it wasn't as user friendly as Krystal by a long shot though. Defiantly a learning curve on that stuff. You had to be very careful sanding between coats. If you hit bare wood in spots you could see the overlap, and had to sand the whole riser again. The other down side to it was it yellowing over time. Don't get me wrong... Thunderbird is an excellent bow finish... I went through about 10 gallons of it before i started experimenting with auto clear coating.

The Auto clear coating rabbit hole can be very expensive, and there are many types. I did find a urethane i liked, but it was too damn expensive. More so than Thunderbird. Then i had a professional auto painter recommend the "Euro Clear" stuff i've been using for many years now.  VERY user friendly, holds up well, stays clear, and half the price of the other stuff i was using. Unfortunately ... like everything else, the price has gone up over the years.

There is my .02 cents on clear coating.    Kirk

You posted while i was typing my last post.... So what type of UV finish are you using? Same brand?  I'll be curious on what you think of durability. it looks good in the photo. :thumbsup:
