I will put up a conclusion video soon.  In the video I rate the different putties I used, and explain what I think makes a good putty.

Mr. Surfacer is much like a thick primer.  I use it to aid in seam filling, to get those bad spots I can't quite fill with other products.  It works great as a small fine filler.

 Some people do use it as a primer, take a look at Biskup's Falke build.  He used it there.

The bondo worked fine, even in the state it came out of the tube.  I am going to use it some more later this week on the Brakiri cruiser. 

That water wall is great, one of my favorite spots.
