so i am not sure if i mad a bad decision today. i disassembled by dana 20 t-case for a rebuild (gaskets, seals, and bearings) and took the empty case and misc. small parts to a local sand blasting place to be cleaned up. after taking them and dropping them off i am contemplating my decision for blasting. should i have taken them to an engine machine shop to be hot-tanked, instead? please tell me i should be fine with the blasting as long as i clean/rinse the case thoroughly.
