We’ve been using DC01NB clear in the shop since it was given to us when it was introduced. It worked out great up until a few months ago when I started getting fish eyes in it. My everyday clear is DC5100 and I have no issues with it. On full spray jobs I use DC5335 and have no problems with that either. I tried switching to another gal of clear, with a different lot number, but I got the same result. I’ve tried using it with DH46 hardener at 4:1 and with DH16 at 3:1 either mix is the same result. I spoke with our rep about it and he hasn’t heard anyone else having this problem. I pretty much just stopped using it altogether. i would like to be able to use it since we do a lot of dealer work and they’re always sending down small items to be painted that they need back in a hurry. Any ideas?
Dh18 is the only hardener I recommend for dc01nb. I have an updated tsb ill upload for you
I have been mixing it 3:1:15% with DH16 and UR60 without issue.
I haven’t had any issues with the clear flowing out with the hardeners I’m using just the fisheyes. I did a quarter on my mother-in-law’s car with some that our rep gave us to try out before it was released and it still looks great. The problem seemed to develop when they switched from the 40 series hardeners to the 10 series. That’s why I tried going back to the 40 series. On Thursday I shot the jamb on a Mercedes ML with it and I got fisheyes so I shot some on the paper and it fish eyed as well. It’s very odd the way it’s happening since its the only clear that reacts this way for me.
I mix it 3:1:15% DH16 and UR60 and have not had an issue.
Sprayed over Onyx, not solvent.I’m spraying over Onyx as well, but I experience it over Diamont as well.
I have no experience with this clear, but how about this…
Is it possible the problem isn’t fish eyes/contamination? Maybe you are getting some micro blistering or solvent pop? I have seen other (low Voc) speed clears get odd looking solvent pop that looks like fish eyes.
If you look in the centre of them, can you see a speck of crap, like you often do with fish eyes?
I’ll look into that. I’ve pretty much shelved the clear but I think I’ll start playing around with it again this week.
Gave it another shot today. I mixed it 3:1:15% with dh18 and sprayed it on a sprayout card and fisheyes galore. I got the same result spraying on the masking paper on the job I was working on. Seeing that I dumped it and cleared the job with DC5100. I’m going to order a fresh gal tomorrow to see if one of the guys may have contaminated the gal.
can you get me a batch number off the gallon can?
Got a new gallon today and made a spray out. I’m happy to sag no fisheyes. Tomorrow I’ll spray some jobs with it and give my rep a call back about the gal I had on the shelf.
hey ive had the same problem to first coat good second coat looks like fish eye glory i usally end up spraying another coat or two and it seems to go away i rarely use it but think its prob moisture getting trapped in the can.
I did a fender on Thursday and I got fisheyes. On Friday a sprayed a body panel and of course no problem at all. No worries on vacation for the week.
