There are people who "flood" their models with epoxy, thinking it adds strength. It doesn't, only excessive weight and expense. If you were building an MMX-powered (1/8 A) rocket from rolled bond paper with poster board fins, the use of epoxy might be considered "over-building". Here is a definition : https://www.thefreedictionary.com/overbuilt ( See #3 & #4 ) 1. To build over or on top of. 2. To construct more buildings in (an area) than necessary. 3. To build with excessive size or elaboration. 4. To make more sturdy than would ordinarily be considered necessary. Dave F.
