hmm...good thing i didnt hold out for silicon powder. i went ahead and got AlGlide. put it on last night. it helped reduce/alleviate the tightness and cracking. but its still there. not the perfect solution, but i guess it'll have to do until something better comes along.
bbtw for those thinking of ordering the kit, i think its a complete rip-off in two ways:
1. you can buy the contents of the kit separately and save $2 rather than buying the entire kit (the instructions included w/ the kit are available as a pdf, and the one that is included is a simple print out of that)
2. you dont really need the tools listed; the tools are used to make sure the hinge is properly seated--you loosen the screws and then open/close it and then tighten the screws again.
essentially all you need is the lubricant which is dripped into the two joints. in all honesty i dont know how special this lube is, but i'm sure if you're knowledgable you could probably find something else to use.
