Sanding Sealer is basically just clear butyrate dope with white styrene dissolved in it.
You can make your own easily.
Balsa Fillercoat is clear dope with talcum powder dissolved in it. Good luck finding Talcum Powder anymore. Corn Starch can be used instead of Talcum.

Normal balsa sanding sealer was nothing more than dope with an additive to help with sanding. The additive was not really a filler unless you bought Aerogloss Fillercote. I have used regular dope to seal and fill balsa grain for years with no issues.

I suspect they did it to avoid a few steps and extra weight to the plane. If you read their directions, they say something along the lines of seal, sand, then paint with silver dope. The silver dope is suppose to make flaws really visible.

Has anyone tried this and how does it compare to the original?
Glad I bought some last year. It'll last me quite a while at the rate I use it. Down to just a couple 3.5 oz bottles of AeroGloss sanding sealer.

I have at least 4 pints and I think a Quart of Aero Gloss Sanding Sealer along with multiple 3.5 oz jars.
Have about the same amount of Balsa Fillercoat in pint cans.
Probably a lifetime worth.
Sig is actually fully acceptable if you thin it properly.

I too do not care to sand silver-colored sealer! I have a reasonable amount of Brodakís traditional sanding sealer, and I guess Iíll switch to Sig. I probably need to buy it sooner than later. Also need to get another gallon or two of lacquer thinner, which is carried by fewer and fewer stores.
