Help me figure out my fisheye problem!!

Hey everyone-
I’m having a problem with fisheyes on a 2010 Honda Civic bumper.
Of course, its black, so that doesn’t help matters.
Anyways, this bumper had a small gouge and some rash on the passenger side, which I repaired and primed.
The rest of the bumper was cleaned, scuffed, and wiped down with a post sanding cleaner (PPG).
I applied base, then I put one coat of clear on the repaired area, and started to put my second on which would clear the whole bumper when I saw the dreaded fisheyes.
I immediately stopped, put the bumper under the IR lamp and sanded everything down again. Cleaned, tacked, started another coat of clear, this time with fisheye eliminator in the clear..and boom..same thing, although not as bad.
I am cleaning my gun with lacquer thinner before spraying the clear..could that have something to do with it?? Could there still be something left on the bummper that the prep-sol isn’t removing? Not sure what to do??
Any help would be appreciated!
cleaning ur gun with lacquer thinner wont cause them, and throw away the fisheye additive. i believe your final wipe down is playing a big role in your problem. use a quality wax and grease remover. make sure to wipe it dry and do not let it evaporate on the surface. also make sure the cloth you use to wipe it on is different from the one you wipe off with. (both being clean and new) finally you may want to use a water based w&g remover like ammonia or alcohol and let it dry completely.
make sure to sand out the fisheyes before retrying, and since your color is black, spray your entire bumper in color. its much easier to repair problems before clearing.
when you spray your clear, spray the entire bumper in even coats, not just the repair area.
Welcome to the site.
Fish eyes can be caused by several things, but to narrow it down, it is from 1 of 2 areas.
1. contamination on the part (sounds like you are taking care of this well)
2. Environment (tools, air line, equipment, rags, clothes etc)How bad are the fish eyes? Are they only in 1 area or all over the entire bumper? Can they be sanded and polished out?
This topic has been discussed many times here…we should make a sticky for it or write up an article.
Thanks for the replies..
Ben- shop lines and filters are all Sata, and have been recently changed, so I don’t think thats the problem.
Mo..I was blending the repair area, so I started with one coat over the new base, and was finishing with a full coat back over the repair area and rest of the bumper.
Its got to be residue left on the bumper or something..I’m also using PPG DX cleaners on the pre wipe and final wipe.
I have resigned myself to sanding it down again and recleaning everything. I also will need to clean the gun thouroughly since I used the FE eliminator.
I have heard of improper wiping technique causing fisheyes, as well as fresh tack rags. never had that problem. Every single time I’ve had fisheye problems was on my old system and it all went back to the airlines.
FE should take care of anything minor, so you must have a pretty serious issue. I didn’t figure out if you had the fisheyes on the start of the last complete clear coat, or if it was on the repair area the first time… which was it?
I WOULD stick to what mocoke said.we some times have this problem.But we no why we have the problem,The cars we work on are on the forecourt and valeted, and the valeters use silicon products.Especially the Tye clean.
Same as what mo said…one other thing…what kind of wipes are you using??? :blink:
are you useing a clean rags? i use microfiber rags and after a while they become saturated with cleaner and will casue fisheyes.
i agree with you, it has to be something on the cover. and use dx1005 cleaner instead of dx330.
