@Pingman posted:@T.Albers, unfortunately, Hobbico HobbyLite Filler is nowhere to be found at least not from any web-based vendor my internet searches have turned up. It's usually shown as "out of stock" and/or"discontinued;" the latter due to Hobbico's recent bankruptcy and acquisition by a competitor offering a similar product at twice the price.
If you have a suggestion for an alternative product, please offer it. Otherwise, I am familiar with the Squadron, Tamiya, and Testor's filler products and will probably try them for this application.
Good Morning @Pingman several years ago I did use another brand of light weight micro filler to rebuilt the upper decks and main cabins of this 1937 RKO movie prop. I appreciated working with this type of filler because it was lightweight, sandable and easily accepted paint. That's why I choose a micro filler again to fill-in the tiny gaps on The Little Nugget's windows.
Sorry, its been a long time and I don't remember that other brand fillers name. I would suggest checking with your local hobby shop that carries R/C planes for a recommendation on their current brand of light weight and sandable micro filler for balsa wood airplanes.
