Hydrospan or Hydroshrink?

I understand the concept of each after reading the tutorial on Customego, but what I would like to know is which product gives the best result? I reason that a larger head reduced in size has better detail than a smaller figure increased in size, but I have seen some of Austin's Superpowers heads in 8" scale and they look great. Also, it appears that the Hydroshrink may be harder to use because of the need for speed and super-cool water. Some Mego-friends insight would be appreciated.

Either system is great but they each depend on numerous factors, including, but not limited to:

Condition of the mold
Pressurizing the cast
Temperature of the products

If you start out with a bad mold neither product will cast properly.

If you do not pressurize the cast neither product will cast properly

And, if you do not have the HydroSHRINK cooled down enough it was cast too rapidly and you won't have time to pressurize it.

Hope that helps.

Peace, Love, and Megos,

Shrinking makes more sense than enlarging because of the detail it captures. Just check out you tube for how to use it.

Austin hits the nails on the head with all the above. There is no way in heck I could get Hydroshrink into a mold, tighten the bolts on my paint tank and pressurize it before it sets up. A better way to deal with Hydroshrink is to use a brushable silicone (you can coat every hour, so you can put on enough coats before it shrinks any more, and buy some silicone thickener for the latter coats) and pressurize the resin while curing. I have had zero luck getting a decent cast without pressurizing. Both are good and you dont lose detail with either. A reason someone might lose detail is because both expel water and you need to lightly blot them prior to molding.

I made a trip to Atlanta today to shop at The Engineer Guy. Since I don't get to the big city that often I picked up a quart of both Hydroshrink and a Hydrospan. Now that I have them it's time to learn how to use them. Thanks guys for all of the great advice.
