Alternative To Bondo?

Evercoat rage or rage gold is what I use. Bondo lasting long has nothing to do with the brand it has to do with the proper prep work. If you have to cake it on then you are not doing it properly. There are other brands through autobody tool mart that are reasonably priced that I'm sure work just as well. It's all based on how easy it sands and how resilient to pin holes it is. Good luck.
