Very interesting topic.
Dont mean to take it off topic too much, but a few people have mentioned grit blasters ....anyone have any info / experience with these to help a newby ??
On the flux issue, I started with Coralite and also Fluxite, and never saw any green deposits, but when I tried others, then it became more apparent - its either the flux, or that I am not cleaning up as good as I should !!!???
Thanks,
Andy
