Grain Filler

[Mad Max]

What is a good grain filler I can get at the big bow store or Amazon?

[onetone]

I use clear shellac. Big box stores have it and quart lasts a long time.

I have shellac and use it, If you put to much on it takes a day or so to dry.
any tips on how YOU us it?

I use a very fine bristled 1” wide flat brush to apply a thin even coat without runs or puddling. Let dry. I live in an arid place so it dries quickly, where there is high humidity dry time is longer. Fine sand and repeat application until wood pores are filled. No tricks really, just persistence and patience. I live off grid so I avoid using hair driers (watt hogs!) but carefully used that would speed drying in humid areas.

I have a dehumidifier in my bow room, I do mine about the same but I don't sand between coats.
I can spray or wipe on a coat every 2 or 3 minutes .

If you use the Zinsser shellac, make sure to get the Seal Coat or decant the others. They contain wax.
You can buy dry dewaxed shellac flakes from Homestead Finishing, Shellac.net or a slew of other places.
The dry flakes are awesome because you only dissolve what you need and you can adjust viscosity to suit the project, not to mention the different tones available.

I use pumice powder, diatomaceous earth or talc mixed with tung oil as grain filler. They all go transparent. Just like any other paste filler, let it haze over and wipe with burlap. Those powders also double as rubbing compounds

Always with the big words!

I'm being critiqued about being bombastic by a guy with 14 posts?
Man, what's this forum coming too?

On osage self bows I use 3 coats of Tru Oil to seal the pores and then 3 coats of spar urethane to waterproof. Jawge

Well,  according to Google,  your diatomaceous compound should lower the bow's cholesterol.???

Yes and it will keep it from and getting worms! And if you really love your bow, you will rub it all over with DE and it will be as shinny as a new car.

Flem... sent you a pm...

[Mad Max]

I think I will stay with the Shellac 

[Longcruise]

Me too.   Don't want my bow to have shins!

[Flem]

What?? Now you want a shiny bow, not a shinny one?

[Longcruise]

My bows are skinny,  but never shinney.

Bow Man will this filler you have spray well with the same tip used to spray the Tbird finish.

Mike most are brushing it on. It dries and is ready to sand in 15 minutes.  You can spray if you want but it dries so fast that does nos work as well. If you do spray you will want a larger tip

From the Thunderbird website description of the sealer;
 "Do NOT wipe down or "clean" with solvents (acetone, denatured alcohol etc.) after applying, drying and sanding on bow as it will have an undesirable chemical reaction."

I would like to see the MSDS for that product. Bow man your website contains no MSDS info?
So is it recommended to wear gloves so you don't have to worry about body oil on the surface?
