"Help!" for: Molding

[HappySalesman]

Hey guys, quick couple questions.

I know everyone seems to talk about Smooth-on products and rebound 25, but has anyone thought of using Silicone RTV?

It seems to be a lot cheaper than smooth-on (http://www.tapplastics.com/shop/product.php?pid=61&) at least from TAP. Has anyone thought of using this stuff?

Also, reading the description it said the viscosity is 60,000 cP. I know some molds require you put them in a vacuum chamber to degass them. At what number cP do you not have to degass the mold mixture?

This is bad and frowned upon and their will be weeping and gnashing of teeth when making molds of armor someone else built without their permission.

Does this also apply for pep files people have unfolded?

Hello !

Rebound 25 is a brush-on silicone , which is what you have to use for molding helmets . Pouring a RTV over a entire helmet would cost loads and loads of money and would be seriously non-economic . A RTV rubber is much better for creating block molds of small parts . Hope that answered your question!

I don't see how those two are related. By the time you mould anything, you will long have reinforced your model. I suggest you read a few more tutorials.

You shouldn't make paintball equipment at all and you won't find much help for that here.

I wondering whether i should use a combination of high quality sandpaper and the rotary tool, just sandpaper or just the rotary tool? Any tips for using the rotary tool would be much appreciated ?

Use a rotary tool first , then sand it by hand starting with a high grit and progressing to a fine grit so you get a nice smooth finish . Make sure when you use the rotary tool to Take you time! I can't stress that enough . Take your time and it will turn out awesome! If you start to get frustrated , sit down and take a break . Make sure to plan out how you want it to look and what your doing before you start . Take a look at the updated version of my advice thread !
