im going to tell you what i just did some testing. most of you know im all about the eagle stuff but use the 5000 trizact as well after the green bufflex. well eagle discontinued the wet bufflex green discs awhile back and now they have gone all dry so i wanted to give this stuff a try first since i am down to my last box or two of wet green. well dry the green was ok, nothing super impressive. it did work and i guess for a 2500 grit it lasted awhile being dry. i decided to try again but this time finish my panel with 1500 grit dry with finishing film as before then try one of these green dry discs but instead dry run it wet....HOLY CRAP! what a difference. this takes the old green wet and 3000 trizacts and blows both out of the water. it cuts about as fast as 1000 grit and im telling you that i bet you could do an entire car with 1 disc. i have done a harley and 3 sportbikes and i am still running the same disc and its cutting like i just put it on. it cuts the 1500 out like butter. ok thats that. after that i took this same panel and i sanded 1/2 with a 5000 trizact and the other 1/2 i did with a black bufflex dry disc but again i did it wet. wiped the panel off and buffed with 3m perfect it compound and a foam pad. there was absolutely zero difference in buffing speed or difficulty between the black bufflex and 5000 trizact. i should note this was on 3 day old universal clear. now as for a price comparison, trizact discs are about $120 for 15 discs. a 3000 disc does about 2 panels on a car. so figure average 1/2 box per car $60. bufflex is $50 for 25 discs. lets go overboard and say it takes 2 discs to do a whole car even though i bet only one. thats 4 bucks to sand the car in 3000 grit. 5000 trizact for some reason lasts longer. 2-3 discs to do the car so figure $20-$30 for that step and again $4 bucks for eagle. i will never buy another trizact disc....ever!
