Chrome powder looking dull & glittery

I am using the OPI Chrome Effects in Great Copper-Tunity and am having a heck of a time. I did my ring finger on my left hand first and did the whole process to see if I wanted to continue with this color and chrome – Two coats of gel color (The Gel Bottle brand in a brown shade) and then a non-wipe top coat, the chrome, second top coat. That first nail turned out pretty good and had the mirror-like reflective finish I wanted. Then as I got to my pointer finger, I realized it was super dull. I started googling and found another post on this thread about chrome issues looking glittery vs reflective and started experimenting based on the suggestions. I’ve tried two different top costs – The Gel Bottle and DND. Both are non-wipe, so that’s not the issue. Then I tried varying how long I was curing. The first nail was cured a full 60-90 seconds using the Gel Bottle lamp. But I tried as low as 15 seconds like others suggested, all the way up to two minutes. Tried different ways of buffing the powder on – makeup sponge, applicator it came with, just my finger, etc. I tried just doing a tiny bit of powder, tried wiping with alcohol first. Nothing was getting me to the original finish of the first nail. I removed the polish on several fingers multiple times to try again and just couldn’t get it. Some were better than others, but most were either more glittery than chrome or just dull looking. I feel like I’ve tried everything except for using OPI’s top coat. I’d be more motivated to purchase that if I didn’t get the finish I wanted with the first nail. Any suggestions? Note: the photos I’m posting were taken almost a week after application, so the chrome has chipped around the edges. Not my best set by any means, but I was getting frustrated and in a hurry lol.
