I have used the spray based lithium grease as well and it worked perfectly fine with my lens.
But of course one should not spray
it onto the helicals. After thoroughly cleaning the old grease off the helicals, I sprayed my new grease into a clean receptacle and then, using a Q tip, carefully and sparingly wiped some onto the newly cleaned lens helicals. A few dabs here and there worked, followed by re-engaging the helicals and twisting them to spread the grease evenly. I found a little too little is better than a little too much in the long run. At first I though that spray based grease would be too thin (but it was all I could find.) Turns out it was perfectly OK.
It could be possible you have applied too little or have not yet allowed it to spread out evenly by manipulating your helical.
