This is 100% accurate especially relating to black’s and dark navy blue colours.
I remember a similar thread on the a.b.o.l and one guy said he double baked black cars, or at the least extended the bake time. I have tried this and it does indeed help.
I notice a couple of replys here say they go from 1500 to trizact, i think that is to big a jump on grit’s 1500-3000, most suppliers advise two grit sizes is the maximum jump on sanding grits.
I have tried many many different dirt removal sanding procedures, dry and wet.
I always return to p2500 wet, 2500 is very easy to compound and polish compared to 1500.
1500 is good if you are wanting that mirror flat finish, but that kind off finish is not really applicable to most modern car finish’s, usually you just want to sand out your nibs and a quick scuff over the painted surface to take the raw edge of the finish.We use 3M at work (because we have to!). For my own stuff I use Megs 105 & 205, and find them far superior.
The initial cut of the 105 isn’t as high as 3M Fast cut plus, but because it is non-diminishing it just keeps on cutting for as long as you want it to, long after FC+ has broken down into a finishing polish.
with all the sanding and buffing i do here in the shop i need the fastest, easiest system and so far to date of all the ones i have tried 3m’s newest system is the best one yet. it does however take some getting used to. once you figure it out it so fast and nice its not even funny. the big thing is the 3000 trizact. i have heard alot of guys say they think its too big a jump in grit but you gotta rememebr its trizact paper so a different animal. if your disc is good, it will take out 1500 scratches in seconds. the big mistakes i was making with it was overusing the 3000 discs. its tough to tell when it stops cutting. you should get a hood and fender out of one disc, usually no more. the other i found, is wipe each panel with a tack rag before starting. if i follow those steps i get a pigtail free finish every time that buffs out with one quick single pass with the buffer. also you guys say you like the meg105 better. i have some here, you know its just the new 3m compound relabled right? the thing with buffing is everyone has their way. you ask 100 different people what they do and it will all be different. i was a little weird on the new 3m system as well, i mean the compound feels more like a polish so i thought how can this even work. i dont have good luck with it on 1500 scratches but thats not the system. stick with the system and its super fast with absolutely great results. i was using presta before and while that system works good, its extremely messy and oily. cakes up the pads real easy, very smeary. 3m’s stuff is so clean and makes next to no mess.
