For months I've been using a thick cut of B-67 in naphtha

between coats of shellac on veneer repairs.  It fills the grain on

mahogany, is clear, and dries fast.

 

The schedule is:
Color match
Brush on 1 lb shellac (usually garnet)
Brush on B-67 (the veneer patches are most often less than 2")
Sand lightly - love 3M Gold 500
Re-coat with B-67 - make color adjustments with Transtints mixed

with alcohol hand cleaner whenever you're not going to sand it off
Top coat with 2 lb shellac to taste.

 

Yesterday, a veneer patch was completely grain filled and color

matched in about an hour.  Even though the color match involved

a fortuitous strip with lacquer thinner.  The grain remained

packed and all I had to do was re-coat with shellac.

 

The Transtint and hand cleaner method will be picked up by Craig ....

Paul taught me his technique for touching up between coats using

Transtints in 70% isopropyl alcohol.  The isopropyl alcohol will

not etch much into shellac and has little or no effect on lacquer

but is still totally compatible with Transtints.  The problem I've

always had with using dyes for touchup is the "bull's eye"

phenomenon- you put the brush where you want the color to go

and because of the thin viscosity of the dye, you effectively circle

the area you attempted to conceal.  You can change the viscosity

of the dye by mixing isopropyl alcohol with isopropyl based hand

sanitizer into a medium you find most useful for picking up and

laying down the Transtints.

 

By the way, I just used a rag to apply Garnet shellac mixed with

ethanol based hand sanitizer...  film at eleven.

Paul here,  it's a micro groop shop here every day.  I'm posting

the photo of the egg carton we use to hold one drop each of 6

different Transtints and small bottles of 200 proof alcohol, hand

sanitizer 3:1 w/ isopropyl, 3 lb shellac, and 3 lb flat shellac. 

When there's a need for a small amount of color, I dip the brush

in shellac or hand sanitizer then in the Transtint. The clear egg

carton makes a swell palette for mixing the right shade.  Apply

directly.  The B-67 came in when I was using it as a barrier coat

to seal the fresh tint.  Like Penicillin, it was an accidental

discovery that leads to my - so far - ideal grain filler for small areas.
