I don't have any problems with DYI as long as it is done properly. I don't understand why you guys are going over stuff that takes 3 coats and doesn't harden enough whilst there is cheaper solution but that's your choice.
What are your sources about the stix factory? You may want to make sure you can reference what you say before writing it down on a forum
The owner of that Stix factory is Dr. Evil, and it is only the first of many that he plans to build around the world. His ultimate goal is to make us completely dependant on him to keep our cameras from dragging us into the deep. My source for that is the same as yours for saying that the paints we are using will dissolve in the water, creating problems for the environment; Or that only those with good cutting tools and a lathe could make a decent camera float.
Why would you care whether someone else's DYI is done properly? Are you Dr. Evil? I'm kidding!
