Jeff:(posted 8450 days ago)I use some of the Sprint chems regulargly. I use their stop bath, fixer, hypo clearing agent, and wetting agent. I tried their print developer and didn't particularly like it. I've never used their film developer. The stop bath and hypo clearing agent are diluted 1+9. The fixer is diluted 1+9 for prints and 2+8 for films. The wetting agent is diluted 1+99. The fixer hardener is purchased separately and requires a Hazmat shipping fee. I don't use the hardener and have never had any problems. They have product information and MSDS sheets at their website at sprintsystems.com.
