is the plastic weld sandable?

did you use adhesion promoter? yes it sands easy

For something nonstructural like the airbox lid, any general plastic epoxy should do well. Definitely use adhesion promoter and get one that's flexible(semi-rigid) so it doesn't crack again. Reinforcement tape is also highly recommended
