it looks better that bare bondo!!! rattle can primer might absorb water but a good primer/sealer is the main part of a paint job, and it will not absorb water until it really breaks down (sun damage mainly), chances are anyone who primes a square like that, still needs to block it and probably needs a final prime anyways and the hardlines will go away it if gets blocked properly and enough. I'd rather see it primed, than in bare metal or rotting in bondo. DO WHAT YOU DO
