LAST record preservative

I have noticed a slight reduction in highs after applying LAST record preservative. However, if I use Disc Doctor record cleaner after applying LAST preservative the highes seem to return to normal. Does the preservation effect if LAST still work if I use the Disc Doctor solution after the LAST solution has totally dried? I listen to my LP's daily and don't want them to wear out too fast if possible! All of my LP's are cleaned on a VPI 16.5 with Disc Doctor Miracle wash prior to play back or treatment with LAST preservative. Thanks for any advice, or feedback!
I forgot to add that I have always used the LAST Stylast treatment with all of my cartridges and records. LAST claims a "chemical bond" between the preservative and the Stylast. Maybe that's why I have never noticed a reduction of high frequencies? IMHO, I REALLY like the LAST product and what it does.
Mofimadness, have you listened to your LP's before and after the treatment of LAST preservative? I clean my new and used LP's with Disc Doctor Miracle cleaner on my VPI 16.5 and then let then dry. I will listen to the whole LP. After I have listen to the clean LP, I will clean the same record again and then apply LAST. To my ears, the high frequencies seem a bit rolled off. I am following the directions for applying LAST. Is it possible to over apply LAST?
Mofimadness, I have LAST stylast treatment. I will give it a try with the few LP's I treated with the LAST preservative. Hopefully, that does the trick. I am new to vinyl and have read so many good and bad things about LAST products. I am just very cautions about these different products. Most of my new LP's range from 30-50 dollars a piece, so I want to make sure that I am doing the best thing to preserve the record, and of course keep the sound quality as perfect as possible. Thanks for your input.
Rick...the LAST preservative evaporates so quickly, I can't believe you could over apply it. In the very beginning, (many years ago), I did listen to many before and afters and was totally sold on what the LAST did. I haven't done it recently because I believe so much in the product I never questioned it. I know there are some who doubt what it does, but to my ears, I really trust it. This has been debated many times over, but I am on the PRO side of LAST. I guess I can let my records speak for themselves as to whether it works. I buy probably 10-12 new records a month, so I understand your concerns.
Rick, I have noticed this also and so I will not use any LAST products. I also won't spend any time discussing this because it always ends up badly. To each his own.
