On FAP-16, the skin to coaming attachment is accomplished by wrapping the skin under the baseplate and using snap connectors (see here for the idea).
On TDY-16, the skin is attached directly under the coaming with machine screws and recessed snap connectors. This is a cleaner installation, but the other method is easier.
