Multispec Clearcoat Peeling: Serious Compatibility Check

Summary for multispec clearcoat peeling Discussion

Clearcoat peels from Rustoleum MultiSpec paint where graphics are applied is the issue Jim Johnston reports: he says Nason clear coat is releasing only in the areas where graphics were added, even on parts that had been cleared for weeks before the graphics were installed. The rest of the clear remains sound. In response, the answerer says the problem is so specialized that the best source of help may be the manufacturer rather than other readers. They also caution against generic brand-switch advice and ask why a clearcoat not designed for MultiSpec was chosen instead of one of the two clears made for it. The answerer further asks what kind of graphics were used—silk screening, decals, or CO2 laser graphics—since that detail could matter to diagnosing the failure.

Q. We recently started using Rustoleum’s new MultiSpec paint with Nason clear coat. Having been spraying a similar product (Zolatone) for 10 yrs, we feel we’ve a pretty handle on the prep and process.
The problem we’ve uncounted is the clear coat is releasing anywhere we’ve applied graphics. This has happened on parts that have been cleared for weeks before the graphics were installed.
Other than under the graphics, the clear is fine. Looking forward to replies, thanks

A. Hi Jim.

A problem of graphics causing a specific brand and type of clearcoat to peel from a specific brand and type of paint is so specialized that you may have to rely on the manufacturer, rather than being able to find another reader who has used this combination and solved the problem. And we wouldn’t want to see responses like “Change to Brand Y and you won’t have this problem” :-(

But I should ask why you chose this clearcoat rather than one of the two designed to go with the MultiSpec? What requirement are you trying to meet that they don’t meet? And what are your graphics: silk screening, decals, CO2 laser graphics? Thanks.
