First post, problem with clear..

hello everyone,have been on here for a while,look on here often.. but first post,have come across a problem, have tryed alot of things to try fix but bit lost, any ideas please, any info would be great..

basically get this in pic, when lay down 1st coat of clear, looks like silicon/grease but not so sure? just struggling to lay laquer down but it doesnt want to lay properly.
I have tried the following:
completely changed laquer, activator and thinners
Have purchased and installed a new air line and oil/moisture filter (now have 3 on there)
New gun wash
Have panelwiped extra






This has happened onthe last 5-6 jobs and its driving me crazy as usally i can get a great glass finish.

It looks like a really bad case of fisheye. Try using a few drops of fisheye eliminator in the finish paint. Fisheye is caused by contamination, but hard to say where you are getting it from, seeing that you are taking so many precautions already. You said you have changed all the filters. Are you by any chance using an inline oiler/water filter? If you are, then there's the problem. You use an oiler through the lines to lubricate the tools, but some guys forget that when you hook up a paint gun, you will still get drops of oil through the lines.

Hey neil

Didn't post this on MR2OC then ;p

Have you recently started using waterbased basecoat?

Reason I ask is I was painting a couple of bumpers in solvent base but run out of paint doh! Had a litre of the same colour in waterbased so thought I'd stick that on I got a very similar reaction to what you're experiencing i assumed that the evaporating solvent separated the waterbased paint. Won't be doing that again

I was just wondering if you hadn't let the basecoat fully cure before applying the clear whether you'd get a similar problem.

Jez.

Are you using wiping cloths that have been stored in a cabinet where ANY lubricants are stored. it does not mater if the oils are in sealed containers or not, over time the plastic "BREATHES" oil molecules and your cloths maybe absorbing them.
I know this first hand, it happened to me a couple of years ago. Clean wiping cloths stored in a metal cabinet on an upper shelf while a case of motor oil was stored on the bottom shelf.
Never again.
