Lacquer thinner removes universal clear

P

After 20 hours or so I sanded some UC and then wiped it with lacquer thinner. It softened and then began to come off. Any thoughts? This didn't happen with Chroma..
 
20 hours isnt much cure time for a clear to be subjected to lacquer thinner. a few days down the road maybe. i have an assortment of sikkens high end clears here and lacquer thinner will soften all of those especially for the first few days. hell lacquer thinner will soften the factory clear on your car. so going back to shines question.......
 
I agree, Jim. Leave a rag with laquer thinner on it on your new car and watch what happens.

If you have to clean anything off, I would use wax and grease remover. Gently.

Since I use lacquer to clean old paint out of my gun it's good to know it will get the fresh paint out too!;)
 
Well you have to compare apples to apples. For instance, many repair clears have lower solids and contain accelerators, which means they cure really fast and can be buffed and kicked out the door really fast, at the expense of appearance and longevity. A very high solids clear like SPI Universal is going to have a slower through cure because it will tend to have a high film build (thick) and isn't overly accelerated, which helps it retain gloss when cured. If you want to slap lacquer thinner on SPI clears, it certainly is up to it IF the film is properly cured, using heat, time, and the proper amount of Polar Accelerator.
 
If you are wiping off colorsanding debris, then use the waterborne (701). If needing to correct basecoat prior to clearing then use the solvent w&g remover(700). The 701 is too aggressive for base.
 
Can't happen if mixed right and temp and metal temp is right for about 24 hours, no way Croma would beat this clear in any test, sorry just a fact.

Urethane reducer will not touch but if you wet a rag and leave it setting the the wick action will cause any clear or factory paint to lift.

I didn't mix it. I bought some as an alternative to Chroma to shoot pool cues. My friend did the mixing and shooting. Cues were left in unheated building in Ca overnight, shot at 4pm. I'm guessing temp never got below 55 that night.

I'm just trying to learn here, not making judgements. My friend has been using Chroma for years.
 
good chance the clear was mixed like chromaclear. if so it was under activated .

beat me to it :encouragement:
 
This happened on pool cues? Should be an easy fix. If it was a car, you might have been stuck behind the 8 ball.

Ba dum-pish ! Thank you, I'll be here all week.
 
Or ask me how universal clear reacts when activated with reducer, that I did while talking on tech line and mixing at the same time.

To keep this clean, don't ask me how I removed the four coats of clear off the inside of two doors over a tri-stage the next day.

Practice makes perfect or so I tell myself.
