Charles,
I didn't want the post to degenerate to a stage where everyone else would end up being guilty of what was being complained about in the first instance!

As you well know I abhor bullying and have voiced this and stood up for you in the past. I was trying to get the thread back on track. So let's do that?

It was because of your posts I used Micro Ballons in the first place. But, there is a point where if you do not add enough balloons to the epoxy it would not sand at all!  Then, if you add too much it cracks. Mixed as per instructions Super fil does not do this. As I said, for me, Super Fil is easier.

I will re read your Gee Bee 3 Thread and search for the formula to mix the balloons to epoxy. It would be great to to sand off in less than 30 minutes, agreed.

Craig,

I use two, cut down, cups. One for the Epoxy and the other for the hardener.

If you go to my builds, you will see I add a tad of yellow paint. I do this only so I don't over mix and lose time which is needed for the application. I use 5 minute Epoxy so I must be quick.

It's kinda like mixing grout, too dry is not good and to wet is not good.

Like cake frosting. God I love white on white cake.

I've never experienced cracking in all the years I've used this stuff, but I only purchase Epoxy provided by Model suppliers, never Ace, Home Depot or Lowe's.

Yes, once you get the hang of this medium and it's application, you can do a model in an hour.

I no longer use tape either.

I don't have the patients others have, one of the reason my building isn't polished as to the fit of each piece of wood.

Tasks have to be quick, at least for me.

The Gee Bee Z I built, there's a photo someplace where I used Micro-balloons mixed with Epoxy, kinda wet and kinda dry, used inside the fiberglass wheel pants as glue.

It's all I ever used. Mixed dry, but wet enough to stick, it goes on like joint compound and sands like balsa.

It's all over my Gee Bee Z. Take a look.

I never apply this over naked wood. Always a few coats of clear Dope or Deft Wood Sealer. I always scratch and clean the area.

I'm having better results applying silk over sheeted areas using the Deft. Others use it also.

The only thing lighter and stronger is wood fillets

I use BIG fillets made from wood but finding the light mushy stuff anymore is impossible.  I have tried 5min Epoxy but it never seems to dry 100%  Superfill is so forgiving and it sands so smooth.

 Howard, any more thoughts?

Use Super-fil for what it is supposed to be used for Fillets (Not glue) It is by far the best it beats epoxy and micro balloons and epoxolite and spackle and the rest. The only thing lighter and stronger is wood fillets. Period end of discussion!

Right on Robert. I agree 100% and use it exclusively.
