Lockey,

Probably not the best place to post this but I've found that epoxy mixed with a liberal amount of micro balloons is pretty easy to sand when laminating foam parts as you show above. Each to his own....lol

If you're using just the tiny bit that it takes to do the trick, like with laminating, then the layer is so thin sanding isn't really a terribly difficult thing. I did some tests on fan fold foam for that purpose. If you use a big pile of glue then it can get rubbery and difficult to sand flush without rolling up in balls like rubber cement.

Why not mix the microballoons with foamtac........ Some guys mix water soulble polyurethane WPU with light splackling compoundsands well and its flexible.....

Foamtac will have its new filling compound out for demo at the Wram Show... Sofaman will demonstate it at the booth...

Haven't tried that yet, but will give it a go.

I do that for a filling compound and it works great. I also add microballoons or light spackle with carpenters glue for filling balsa with very good results.

And a mix of WBPU (Minwax) with acrylic paints seems to help adhesion to foam some.

Now, back to the contest.........

I have dealt with these people before and they are very efficient, so I have ordered 4 bottles and they are already on their way to me by UPS

By the way … do you have any tips for storing this? … also, can it be used for gluing CF rod/tube into a wing? Or should I stay with using epoxy glue for this?

Lockey

PS. How does it sand?
making a channel with solder pen for carbon fiber rod using foam tac and mpf (4 min 59 sec)

Hope this helps

Pete

New Filler Questions:

Will it be more like lightweight spackle or Gorilla glue?

Will it have adhesive strength like FT or just filler properties?

I would like a filling adhesive that adhered like crazy, filled what you wanted and then...stopped. No crazy foaming action need apply. Oh, light weight would be nice, too.

Hi Buddy,
The "old" version has a purple label while the new has light blue label, and no matter because the old version works well just takes a little longer to dry. I wouldn't worry about it.

Great minds think alike, rcrich. I just started cutting a modified Sumo to look like an angry bird. Any chance to get a photo of your wing shape?
