You can still fin the older style filler at the Super WalMart stores.
Look for the orange lid!
There is a new formulation (CWF MAX) that is much grittier and harder to sand.
I've already marked the water to filler mix ratio on lid -
1 Part Water, 2 1/2 parts CWF.
This mix is a good starting point for a brushable balsa filler.
Is the ratio by volume or weight? Thanks!

Deleteit's by volume.
Thanks! I did volume too, but weighed it, to make it more repeatable than teaspoons. 10g filler to 2.4g water is 2.5 to 1 in volume. I had horrible luck with CWF and abandoned it (too hard to sand, especially on tubes.)...until multiple posts from you convinced me to try and mix 2.5/1. Have done 3 fin sets and they are coming out nice! Thank you.
DeleteI have yet to try this ratio on tubes. FUBAR'd a tube set with to heavy a ratio of CWF...tried timbermate...that went MUCH better. I will now revert to the CWF ratio on tubes and try it. Again, thank you!
