It's pine wood derby time again and i have a question. Last year i had some product around the house that was left by a contractor, it was in a blue tube and I can't recall what it was called. I used it to fill the holes that i drilled into the car where i inserted weight.
I remember the contractor told me it was "just like" window glazing but i know it didn't have that on the tube. It worked so well that i would like to use the exact same thing but can't recall what it was. Would wood filler work as well to fill a 1\4" hole?
This stuff i used last year was perfect after i sanded and painted, you could never tell where the holes were. Any ideas?
