RED LABEL ABRASIVES 3000 GRIT WET

I noticed that on the past three jobs I have done there have been pig tails after using 3000 grit wet Red Label Abrasives, I know for sure that it is the 3000 grit disc because I hand sanded wet today on a bumper up to 2000 then the 3000. Does anybody have a good brand disc in 3000?
 
I haven't had any luck with the cheaper abrasives in the finer grits for the reason you mentioned. They also seem to leave deeper scratches than the grit indicates. The 3M Trizact 3000 and 8000 system works really well, expensive, but worth it to me because it saves time.
 
I've tried the Mirka Abralon 3000, and it's not bad, but like most Mirka abrasives, it lasts about half as long as the 3M for me. I've used the Indasa up to 2000, and had issues. If I was going to try another 3000 fabric/foam disc, it would be the Sunmight. If you are more comfortable wet sanding by hand, there is certainly nothing wrong with it. I have only started sanding clear with a DA in the last few years, but I am always open to more efficient or effective ways of doing something.

I’ve been using the new Kovax Buflex Blue K-2500 after 1500/2000 with good results, I’ve used it with its dedicated interface pad and a water spray bottle the same way I use trizact and it works great. From the Blue K-2500 I have used Trizact 8000 and it does speed things up, haven’t touched the wool pad since doing it this way.

Are you guys using the Bufflex 2500 dry or wet, The site says it is for dry sanding?

I’m using it the same way I use Trizact (water spray bottle) and it’s working out good, even with its dedicated weird interface pad that has no Velcro and feels like felt, the disk stays put and doesn’t come off the pad. The jump from the blue Buflex to Trizact 8000 seems to work out fine.
 
Don't mean to hijack this thread but since this is about sanding discs I thought I would share. I am working on a hood now that I sprayed 4 coats of universal on Saturday. Opened it up by hand Tuesday with 800 and then 1000. Then yesterday I hand sanded with 1500. Then I used the green bufflex wet and then 5000 trizact. I started buffing with a wool pad and sonax and I am telling you I can't get the scratches out without doing some hard buffing (at least 3 passes with wool). I can see scratches from the palm sander which means it is the green bufflex. Has anyone had this issue before with bufflex? I have used this system countless times and never experienced this. Normally its like butter. I am so confused.

yes and no. what i have had happen is the 5000 discs never starts to cut. i found that, atleast with the 5000, it doesnt like soft and fresh clear. if i try to sand fresh universal some discs will never start to cut. they make no or very little slurry. not sure if its instantly clogging or the tips of the pyramids dont wear away to make the discs cut....no idea but whatever it is, it sux. you prob ended up with a 2000 green finish. i have never had this happen with harder clears and only when universal is less than a couple few days old and even then its weather dependent. winter with low humidity and universal stays soft for a very long time.

Never had a problem getting out the green bufflex scratches, but I've sure had problems skipping from 1000 to 1500 or Tolex. The 1200 eliminates a lot of problems for me, and if it's slick I just start there. Are the bufflex scratches pigtails like maybe a piece of trash got under it? Like you said, usually the green bufflex would buff like butter with a wool pad and sonax.
 
Just an update on my end. I let the hood sit in the sun for a full day and came back another couple days later and hit it with 2000 grit by hand and then 5000 trizact and it buffed out fine. I normally do 2 to 3 coats of clear and can cut and buff a couple days later. Even though it had been 4 days I guess that extra coat or two of clear slowed things down a good bit. A full day in the sun and waiting a full week fixed my issues.
 
I've found that when I sprayed Universal and flow coated or had a high number of coats that waiting a minimum of 2 weeks was kind of a personal guideline. Getting right to a panel with multiple coats just didn't work for me personally. After that amount of time it was much easier to finish out.
