what plastic bits?

 

thank you! so i gotta find out where to find some of that haha

 

Napa

 

Oh damn, i was on my way to the nuclear time travel plant turning around...

 

Well, i mixed hydroflouric acid 50/50 with water and dipped the cores in there along with my manifold haha. let the cores sit for maybe a minute each, then took them out and dunked in straight water.

dried off immediately after that with compressed air and they were looking muuch better. a good wire brush helped to take off any other clumped up oxidation and the cores are sitting in my manifold with new zzp o-rings now.

thanks for the advice guys!

 

does the hydrofluoric mix remove hulksmashes as well?

 

not at all! be careful
