Robert Downey Jr. Covered in Rubber/Latex… That Got Your Attention!
Check out how they use the latex to create the effects you saw in Ironman. They layered the applications so they could sculpt the latex and create the dimple where the arc reactor would be placed. The latex is then airbrushed to look like RDJ's skin tone and details like scars, etc.. are added. It's a pretty cool process. How do you apply to be the person who gets to slather Robert Downey Jr. in latex???
