I've been having excellent results with the DS-10 trials I've been doing andit seems very versatile so far. I've had these questions in mind and thought I'd pose them to Ryuji in the list as others likely share some of these... Have you done any extended life tests when bottled up in storage? I sometimes have gaps in time when I'm less likely to be consuming things. I've had good results at 1:1. Are further dilutions successful for you and do you have an idea on minimum stock per roll that you would consider adequate? Have you found any additional success with varied agitation routines? I've been using the Xtol x 1.2 factor plus pour times as a starting point with 1 minute, 2 gentle inversions as is a habit after some testing settled me into that routine many years back and it simply has become my developing behavior for general use. Is the DS-10 able to be mixed at any higher concentrations? The salicylic acid seems to barely go into suspension as is so I can guess that the answer is likely "no"? ============================================================================================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
