fish eye problem!

I just sprayed SPI epoxy over my body work after blocking and filling. I have fisheyes pretty bad in some places. How can I keep this from happening? How do I fix this? I used SPI waterbourn degreaser before I laid the epoxy over the bare metal and had almost no fisheyes. I am afraid to use any kind of degreaser over body filler because I am afraid it will get absorbed and cause problems in the next coats. Help!

I use fast evaporating wax and grease remover if you are using a waterborne cleaner over filler I dont use a cleaner over filler then you may be trapping contaminates because water evaporates slower then solvents or you may have oil or water in your air lines one other thing make sure that you have no silicon products where you are spraying

Not saying this is your case but i have seen body work with pin holes in it and people think its fish eyes from wax/grease. Blow your body work off and look very close next time to make sure arent any minor pin holes. good luck

Work environment and details. I am prepping a car form paint. I have other cars which need engine work, trans work, etc. I will not touch anything oily or with trans fluid in the shop even if it is in the room next door till the car is painted. I had to work on my tractor but I did it outside. I took the tools out but they do not go back till cleaned with thinner. Oils, hyd fluid, etc become airborn, and get transfered by touch just like the common cold.

Once working on the tractor I never go back in the shop. The cloths are washed seperatly from cloths I use to sand and work on the car I am prepping for paint.

Floor is clean and painted. Even though it is covered in paint, primmer, etc the area I am prepping the car is nopt an area I work on cars.

No one is allowed to touch my car in primer. I only touch it withy gloves. It kills me to watch these car shows where everyone touches a car being prepped for paint. I won't touch a car with my bare hands and I don't let anyone else.

Details.

I don't think they are pinholes (some may be). IT is even in places that don't have filler. I wiped the car down with a tack clothe before I sprayed. I bought it from NAPA in thier autobody department. That is the only thing I did different from my previous sprays. Could that be it? I don't have any silicon in my garage sO I don't know how it would have gotten on the car. I do have two PIA cats that could have walked on the car and tracked something on it from the floor.
I guess my original question still stands. What is the best approach for fixing this? Won't sanding it just smear it around more?

If it was me, I would sand with 180 today to smooth them down, wash with the waterborne and dry, let car set one hour ans spry more epoxy if needed or go to 2K primer.


With you having fish-eye here and there, kind of tells me it is not a airborne contamination problem but an area problem.
Cats did not do it!

9 times out of ten if epoxies fish-eye with first coat (right away) its gassing and usually caused by the wax and grease remover looking dry but still in pours of metal or the sanded paint.

This is normally a problem when doing a car at night when sun goes down and humidity goes up or if it is getting ready to rain or in southeast where there is no such thing as humidity under 110%.

Also you might watch the next application as epoxy is sensitive to air pressure unlike other products and if you see this start to happened up the air pressure at the gun 3-5lbs.

Barry,
Will your W&G remover soak into the body filler and cause problems?

Any wax and grease remover can.

Unless it has enough time to dry and looking dry does not count.

Even on a hot day down here, after i degrease one that is skimmed from top to bottom before epoxy, i blow dry and let sit for a good 30-45 minutes.

Some times you may never find the cause. One time we had a bad batch of gun wash, It takes a lot of paint jobs to go through a 45 gallon drum. There is fish eye eliminator you can get to ad to what you are spraying.

I never add fish eye eliminator to paint, I don't need another additive to worry about. Good clean prep practices, and sound equipment and paint area procedures will take care of most problems.

I sprayed again last night and had more fish eyes, just not as many as before. I washed the car with SPI W&G remover and let it dry for about 3 hours. I blew it off, wiped it down with a tack clothe, and shot more epoxy. I noticed that when I sprayed a test spot on my garage door that I had fisheyes in my test pattern. I am pretty sure that the problem is coming from the gun. I mixed my paint in a plastic mixing cup that I bought from Lowe's. It has been sitting on my shelf for quite a while. I mixed the paint with a wooden stirring stick from Lowe's as well. I am betting that I am getting contamination from one of those two places.

Could very well be, it doesn't take much silicone or other contaminate to produce fish-eyes.

I have my shop divided into 2 airlines. One for paint/body one for working with other air tools. The paint and body side have no oilers and I never oil my paint and body tools. I also use a line drier. Not saying you do but was just a thought.

If you can't find the problem fish eye eliminator will help until you do find the culprit, like I said we had to go through the entire 45 gallon drum of gun wash. We changed air lines and all sorts of stuff, even thought it was from cars coming in that had Armorial in the interior but once we got a new drum of gun wash the problem went away.
