I recently helped a wheeling buddy put a cage in his TJ.
Anyways we fit it in, tacked it up then pulled it out for welding.
We then reinstalled it and finished welding in the vehichle.
Everything went great untill he tried to paint it. Paint fish-eyed everywhere. Tried again after re-cleaning it,.....fish-eyed again
:confused:
Same thing happened in mine after I added some extra spreaders. Paint kept fawkin up!
What causes this? Is there a charge left in the tubing after welding? If so, how do you get rid of it?

if there was a charge it should be transfered into the ground if you grab it with your hand. Maybe its just a short in the electrical system that is drawing very low power through the jeep (the cage could be the least resistant path to the battery for the ground) What temperature are you guys working in? that could have a big effect on it

Did you use primer first? Paint by itself won't bond to bare metal, but the primer will actually etch itself into the metal. THEN you can paint it.
And if you used anti-spatter spray... that stuffs essentially oil.. and paint dont stick to oil

This is true! If your using any kind of quality paint I would throw down some good primer first. Good primer makes a HUGE differance. I used cheap crap I had laying around 2 paint 2 steel wheels then used a more expensive automotive brand for the other 2 and after a year of use the two wheels with good primer still had all the paint where the other two the paint was peeling off

Temp in the garage was about 70.
:D Yes it was primered first, I liked that one Dude.
Enamel paint.
Two different Jeeps, two different days, same problem.
If its just my luck, I wouldn't be surprised.

it's gotta be bad surface prep. Ya didn't grap it with your greasy paws did ya?:D If you redo it, use 'etching' primer. It cost more, but it makes a big difference in the durability. i used some rattle cans of this stuff from Tractor Supply Co. cans were about $10 but they cover well.

Was it the same can both times? Was it the first coat that did it or the second?

Are the primer and paint both the same brand?

I think you guys are onto something with the primer quality, at least with my friend's cage issue. It was cheapass Tempo paint.
I wouldn't be affraid to bet that the trouble I had with mine was a solvent base issue.
As for surface prep (cleaning) I had gone over it several times with thinner until the rags where clean.
Thanks for the help guys. :smokin:
That really sucks on the last coat of a rattle can finish.. especially when its been turning out really nice. Had to start over again.. making sure all the cans were from the same batch.
