As above, make sure you are using wax and grease remover correctly.
Any thing with oily of silicon substances can contaminate, the rag you use for wiping or spraying armorall type products around the time of spraying.
I think your shed would have to be pretty hot and humid for a closed bottle to contaminate the surface but in saying tat I had 4L acid in the shed and over time noticed things starting to corrode, removed the acid from the shed and problem solved.
Gun packing lubrication but rarely.
The air line been used in industrial applications with air tools?
Speaking of air tools, I used an air tool on a roof once and it fish eyed like crazy when I primed, I quickly washed the roof with thinners and started all over again.
Air tools that have been lubed will exhaust a very fine mist of oil everywhere.
Fish eyes are not caused by moisture, the water looks just like water bubbles or come thru later as humidity blisters.
I havent used any cleaning products in that shed for months, there was a bottle of engine oil sitting on the shelf near where i was painting but it had a lid on it. The shed is fairly cool at the moment, since its fairly mild weather. I used fresh clean rags, but maybe i'm not using enough wax n grease remover and its drying before i can wipe it off completely.
I replaced the air line after the last air filter incase the line had been contaminated from using air tools, but these panels havent had any air tools near them. I've never had any fish eye problems with primer, but maybe thats because its a lot thicker than top coat.
Yeah i figured, but there was potentially a water problem as well. After my compressor had been running for a long time using my sand blaster i noticed condensation coming out the end of the gun, i figured that might have been able to carry contaminants onto the paint and also cause humidity blisters.
by fisheye do you mean there is wax? if there is wax in the air no matter how many times you use wax and grease remover it will not solve the problem. it could be anything if your shed door is open and your misus is cleaning the house with mr sheen or anything like that and the house door is open it will flow into the paint. i have seen a car interior being cleaned 40m away from where we have been spraying and the panels have waxed up from it. if anything a heavy coat will cover the wax spots. if spraying in a shed clean it out wash everything down. i had this problem in my bros shed he is a mechanic and his shed is covered in oil and crc and shit like that ruined everything i painted and had to start again.
Yeah, i think its silicon/wax/oil. I'm not sure if ill be able to wash the shed down but i should be able to blow all the dust out with the air compressor. Ill head over to bunnings tomorrow and buy some drop sheets and ill hang them over all the walls etc. Maybe that will stop the contaminant. The weird thing is it's only really effecting things i paint in top coat, the monaro was painted in clear over base and the base coat went on perfect and the only problems with the clear was orange peel and a bit of dust and bugs. Maybe the clear isnt effected in the same way because its a lot thicker than the top coat?
Could it be possible that the air compressor is sucking up the contaminent from the other shed. I've painted in both sheds and had the same problem but the air compressor stays in the main one and i just run the lines out. Would the wax/silicon/oil make its way through all 4 filters i'm running?
My misus was lying on the lounge all day studying, damn i cant blame her
