!!! help!!! paint reaction fix needed asap

bex

Mac-Valve Maestro!
I have a huge paint reaction. (crazy pathing style)
Seem to be situated around The cars and a little bit on the tickets but mainly cars.... Argh!!!!!

Normally I'd. Curse. Sand down re-do. Only way I know how to get rid.

But this is different....
*This is MY cars door (so quick fixes and short cuts allowed)

*it's in a show in 2 days time to show off my airbrushing skills. (the same show I'm doing my first ever live demo for airbrushing at.)

*i still need to paint the other door. So don't have time to sand back and re-do. (also worried the other door will do the same as I can't work out what or why it's reacted.
I don't know whether to laugh or cry- (at this stage cry if most likely I can't see a funny side.)

anyone with any amazing idea to quickly and easily make it less visible (At least) till after the show I would be eternally greatful.

wow.....that stinks....looks like moisture is bubbling up clearcoat?? my guess..:depressed:
 
While the picture do show what has happened I need more information.
what is your primer , Base coat , art work and clear. Brands and types.
The bubbling can be caused by a lot of different things from not letting a waterbase paint fully cure and clearing over it Kind of like what Boneman stated , To you laid you clear on to wet and to fast or no enough flash time between coats.
To you cleared it out side with to much humidity in the air which again trapped water in the clear.
That is why on automotive I always will suggest a good intercoat clear go over the art work prior to any clear coat being laid down .
It locks the paint down underneath and give less chance of something like this happening.
Also 2 days before a show and you are taking afresh paint job to it?
Are you painting in a heated climate controlled paint booth?

Thanks for replying - if so -Can the moisture get into the paint over time The cars reacted The most And They were painted first so about 2-3 days ago? Or could moisture get into the clearcoat whilst It's been standing maybe lid not correctly Tight on tub etc...
Any ideas to reduce the visibility of the reaction now???


Mr.Micron. I used same primer I used on the rest of my car no issues. (already painted bonnet/wings /front bumper was also base in an automotive Black paint also no issues..
I use Waterbase airbrush paints and recently Changed from wicked to inspires new h2o (which have also used a few times previously with no issues used on bumper no issues) the clearcoat is a 1k upol clearcoat (not my favorite but as I paint in my workshop at my house and can't use 2k. Until I get more customers so can,afford actual unit etc etc.) (hopefully this show will help if my work actually. Looks decent that is) The reactions seem limited To around the cars and tickets. Regardless of paint brand used or colour or build up of clear. Etc. It reacted instantly from first passing over of my coat of clear.
thanks for replys extremely greatful for any advice and help. .

All I can think to do is scuff back (scotch bright pad) slightly. And another coat of clear. So it at least feels smooth on the surface.???????????
 
I would suggest, maybe, a quick cut down with a good cutting compound, after first sanding with high grain [ 1500 grit ] sandpaper.
scuffing with scotchbrite, after sanding might help by cutting down uneven bits.
Either way, a bugger of a job, mate!
Get some heat into the work area will help keep the clearcoat flowing better, and reduce drying time.
From what I can see, the reaction primarily apppears to be between the artwork paint and the clear.
Maybe solvent incompatability issues?
Your fix might work, IF you can reduce the ridges to a point where the next clear can cover it.
It might still be visible, even though you can't feel it!
 
Hmm I have had issues with 1 k and com-art, Then started using intercoat clear prior to spray the clear and the issues went away.
I have not use Inspires H2O yet, But it may it looks like the same thing I would get with Com-art.
You did wipe down the area after art work to remove grease and oils from the area.
Not going to be a fun fix.

I agree, besides I think you have no choice due to time frame, you could always blame it on the bloke who did the clear coat for you..... ;)
Just a thought, was all the previous coats properly dry before applying the clear?
 
OK, that isn't an oil on the surface problem, that wold cause more a fish eye effect - paint won't stick to the oil. I also doubt it is water on the surface. I asume you haven't taken it outside. It looks much more like a reaction. Is there any filler underneath? For a fix, you could try cutting and polishing it out but you may risk cutting into the design, do so with care. Due to the time frame I think you are caught between a rock and a hard place. I wouldn't use scotchbrite, rather wet sand with the 1500 grit... and park it away from fingers if you can!
 
it looks as though its worse where the thick dark areas are ......like all said.....light sand 1500-2000grade and then polish.....thats what i would try....heat lamps and heat gun to cure completely first...
 
Looks like it has pickled. That could be because the clear wasn't compatable with the rest of the paint, or maybe if you used a solvent to clean the base coat it could have reacted to that, the base coat may not have been properly dry, or the clear has been applied too heavy. How was it applied ??? To heavy a coat of clear applied quickly will make wrinkles etc appear because due to the weight it can sink and sag as it dries. Can only think to wet and dry it smooth if you can without damaging the artwork, and trying again.
