Never heard of it, but is probably just retarder. If it absorbs the moisture, then where does it go?, is my question. MarketingNo, it was moisture scavenger, somthing like this: https://medallionrefinish.com/products/refinish-products/additives/moisture-scavenger
Oh, I thought that was how you solved your problem, my bad.I did/do have and air dryer, but moisture wasn't the thing giving me problems if you read back a few posts.
Moisture was ebaypdllc's problem which he solved with moisture scavenger.
More than likely it was moisture in the air line. And yes it can get smaller as the water evaporates. Moisture traps (piping?) and a filter at the gun is not ideal.I have sprayed up a few times now and never had an issue. If it was moisture, would they be getting smaller over time?
Read this fileJust sprayed a car with UV and I also have some bubbles. I put on 4 coats but I think The bubbles were from the first. i let the base dry for almost 24 hours and waited an hour between base coats. i shut off the few fans I had running as soon as the air cleared. The temp was around 70 with 70% humidity. I used the slow activator. it has been 24 hours since I finished spraying the clear and some disappeared and all are much smaller now. Any ideas? I have a moisture trap at the tank and one on the gun. I have sprayed up a few times now and never had an issue. If it was moisture, would they be getting smaller over time?
i have had it drying as slowly as possbile. Would it help at this point if I could get the panels hot?More than likely it was moisture in the air line. And yes it can get smaller as the water evaporates. Moisture traps (piping?) and a filter at the gun is not ideal.
Solvent pop (as I know it) happens as you are spraying. You can literally see it "pop". Generally there is a pretty small window for it to occur. I can count on one hand the number of times it's happened to me over the last 25+ years. It generally happens when temps are very high and/or when you are painting in a booth with too much airflow, or you are using too fast a reducer for the conditions. Cheaper products (clears and urethane reducers) are more likely to be susceptible to it than are premium reducers and clears like SPI's.
Folks confuse solvent pop often with several other things. Moisture in the lines and fisheyes (contamination) being the two most common things confused with solvent pop.
Doubtful IMO. Take some pics of the problem areas and we can go from there. If you can, take the pics in high resolution and upload them to something like Google Drive and link them. Hi res will help us actually see the issue.i have had it drying as slowly as possbile. Would it help at this point if I could get the panels hot?
First let me thank you for all your help, I really appreciate it. Here is a link to a picture with one larger and one smaller bubble (very difficult to take a picture since the clear has soo much gloss)Doubtful IMO.

Yes it is. Right after I sprayed they were more domed (like a mosquito bite) but settled with time.I can't tell what it is. Is it raised up above the paint surface?
What can I do to fix this (Cut and buff, sand with 600 and put on another coat of clear, etc.)?Water from the airline they will shrink but not be gone and can show up as white spots after a buffer heats them up or after a few days in the sun or a few weeks.
Only hope is give car 5 to 7 full days of sunlight before you wet sand or buff.What can I do to fix this (Cut and buff, sand with 600 and put on another coat of clear, etc.)?
