I’m doing a product design for school, and it consists of a solid color underneath what would be a frosted, translucent, silicone overmold over the whole product. However, I’m not quite sure how to show this finish on my model. I’m going for something that looks like this: http://al-fatima.co.uk/images/DSC00987.JPG. I’m going for the look over the feel, but having both would be a major plus. I’m intending for the silicone to have a few millimeters of thickness on the product itself. The following are options I have considered and problems that may arise from them:
Casting silicone over my painted model - I have never casted anything before and I’m not sure how I would pull off casting the silicone only around my model
Styrene - Vacuu-form the two halves of my product with clear styrene, either sandblast or paint it, and then encase my model with the 2 styrene halves. The problem with this is that I’m worried adhering the two halves together with solvent might get a little messy and I’ll end up with a messed up looking part line down the middle. The benefit of this method though, is that the styrene will give the thickness of silicone I want to convey.
Layering clearcoat - this is probably the easiest method. I’m thinking about getting some type of clear coat or clear resin that will go on thick, and spray with something to make it look frosted. However, I tried layering just regular clear coat, and it doesn’t build up enough.
So guys, I’m really stuck. What do you guys think? Any suggestions for these methods? And other ideas?
