Clear is Cloudy

Painted a gold dodge intrepid in pieces. Painted it black, black epoxy sealer , base coat , 4 coats SPI Clear. Wet sanded 1000, 1500, 3000.
Compound wool, 3m compound . Sure Finish foam cutting pad , black waffle pad dark glaze, blue foam 3m ultrifina. Turned out beautiful.

Car was picked up 6 weeks ago , owner calls and says roof, hood and some of the quarters looking a little cloudy now. He noticed yesterday . I will look at car in a few days .
Possibly solvents escaping and now showing up ?

I told him not to wax for 3 months, hopefully no car cover put on . Hopefully a good buffing should take care of this ?? I reduced clear maybe 5%. I have heard to use a 50/50 alcohol water mix in between compounding steps to see what you really have because some compounds and polishes have fillers in them ?
Any advice appreciated .

3m has fillers in it's buffing materials. The fillers may have hidden some areas that weren't truly buffed out and when the filler dried out they were revealed. Could be that or blushing, but blushing is rare and I never really see it to be honest and so I'm not sure if blushing is visible right away or after a certain amount of time.

I had this same problem with 3m stuff. Washing your car after compounding helps to give you a true read on what's really buffed out cause the filler additives make it hard to judge. You can think it's all done but spots will come back. It's a huge turn off.


Blushing is caused by hot humid weather, moisture, cold substrate surface, excessive air, too fast a thinner/ reducer. Basically moisture trapped under/in your paint and makes it look cloudy. I read about it but RARELY see it but I'm sure it's more common in places with more humidity.

Sometimes if you polish immediately after sanding you actually heat seal the surface up tight and then when it tries to gas out it can't "leave" and it will dull.

If you sand with 1000 and wait a day(24hrs) for it to "breath" to then follow with 2000 and then polish it will buff easier and be less likely to dull down.

Rx , resand with 2000 and rebuff with slower buffer speed.

yeah sounds like the clear might not have all been cured i cant remember what clear we used at the shop i was at but it would do that sometimes and after a light sand and buff it would come out sometimes you dont have to sand it but i think it made it go smoother. when i was in school i was told on the newer paint not to use wax though cuz it can make a green house effect on the paint and cause it to oxidize faster. haven't heard of the alcohol mix ill have to try it

in the summer, i cut open the next day after paint and let sit all day in the sun (maybe 2 days) after sanding with 800 or 1000. pull in, finish cutting all the way to 2500-3000 then wait another day and buff. if its a nice day i throw it back outside for another half day/day before i buff. nothing cures like some good uv rays.

you put on 4 coats of clear, and buffed too soon. a good re-buffing with good compound will do the trick......its possible that you MAY have to run over the affected surfaces with some 3000, then buff.

that's a great post above, Milo. I never thought about that cause we always have that safe guard in place to let it cure a little but know a lot of shops who want it gone. Maybe I've been just blaming 3m aimlessly while it was out-gassing all along. Learn something everyday. Thanks for your input and correction.
