I came to the conclusion that for very small parts the powder gave it too much texture. I expected the powder to dissolve in the liquid but it acted more like a fine sand. I can see this is no problem when using as a filler that you would be sanding anyway.
I kind of figured it would be rough, but at least now we know. Thanks for giving it a shot anyway Mike!
Mike, great tutorial I bought the stuff after seeing it used in your momad. What is the best way to build it up to do custom fender flares or larger apllications? Hoping to find a way to use it instead of balsa wood which I always break.
Kyle, there are two ways to build something up using this filler. One is the method I used on the Momad to fill in the backside of the wheel arches on the Magnum body, and the other is applying it straight to the area you want to build up. On my Concept Charger, I added a rear spoiler made entirely of this filler. I placed a piece of tape on the trunk (Since I wanted the spoiler to look like a separate piece, I made it removable) and laid the filler on it until I had the rough size and shape I wanted. If you were doing wheel flares, you could just lay down some filler where you wanted it on the plastic. Lay down some filler, and let the first application cure (About 15 minutes if it's not too thick) and apply some more, building it up until it was slightly larger than what you wanted. If it's a thick application, let it harden overnight, then start shaping and sanding it. Here's a few pics of the Charger's spoiler being made, the only limit with this stuff for body work seems to be your imagination!
The filler built up into the rough shape of a spoiler, this took 3 applications to get the thickness I wanted...
After a little rough shaping.....
The final shape prior to fine/finish sanding...
And a shot of it off the car, it's not completed in this pic, but you get the point. From here, it was finished off, then super-glued to the trunk. I cut the ends off and attached them to the quarter panels, making a 3-piece spoiler completely from Acrylic Filler!
And the completed model, with the spoiler in place!
