Anyone have anymodel filler.jpg experience with this filler ? Or the Hobbico brand filler?
 
Yep... been using it for years on rc planes... now on balsa fins..lols, Its super lite and sands like drywall mud
 
Elmer’s wood filler watered down to a thin paste solution works well also. Easy to work with too.

I found this on Tower Hobbies site. I was ordering some T-pins and push pins for building balsa planes.Thanks for the input.
 
I have never used the filler from Deluxe Materials, but have used the Hobbico brand for many years. It has worked good for me. One thing that I like about it is that it does not dry too hard. I have never had much luck with using a filler that dries rock hard on a soft wood like balsa. I do thin it, as that seems to fill the pores better. If using any water based filler on fins be sure to do both sides at the same time. The balsa fibers will draw the water out of the filler and warp the fin if only one side at a time is done.

That's why I'm generally cautious about using CA on balsa. Hard to sand the rock-hard CA without destroying surrounding wood. I have adjusted my nose cone CA technique to accommodate this, namely to finish with a coat of CWF, so I don't need to get the CA layer perfect.

Can't find the older style filler that was real wood.

I actually found a small tub today when I was at ACE. Nice its a small 4 oz too. Better chance it doesn't dry up and/ or get hard pieces in it.The Walmart upwood filler.jpg here hasn't had this type in awhile. And yes, I do fill over primer. OH NOOOOOOOOOO!!!! I have had issues in the past with the filler soaking into the small half BT and swelling them. It is water based. The primer gives it just enough protection
:Wink:
