riry, which vectra spray is it...is it item E on the site?
So... I have the results of my treatment tests.
LMB Miracle Shield- ruled this one out from the start. Didn't want to use a rub-in product for the PS1 leather.
Apple Garde- tested this on a small section on the underside of the top flap. This product did not alter the color at all, but it left a faint greasy feel to the leather. Decided not to go with this for the entire bag.
Vectra Spray- purchased this product after doing some research here on tpf. Messaged ****** about it, and E gave it the thumbs up. This product darkened the leather when initially sprayed, but it dried in a few hours to the original color. The best part about Vectra? It did not affect the texture at all. The leather looked and felt exactly the same as before treatment.
I have now treated both my Maize and Smoke Mediums with Vectra. No need to post pics of them because the before and afters look the same.
Miscellaneous Thoughts- before treating my Maize, I got a tiny spot of denim transfer on the back of the bag. LMB Botanical Cleanser took the spot right out and did not lift any of the Maize color. I treated the entire bag with Vectra after that, and have not had any denim transfer at all. I wear dark jeans every day and have been able to wear both my Maize and Smoke with no worries at all.
