I couldn't be the only one out there that's ever experienced a shiny, solid circle around their bullseye repair. Is it the lament?
Resin? curing ? What?

I did a repair today that was perfect except for this clear, shiny circle about the size of the seal (Delta equipment). You can hardly see it from the outside but can see it clearly from the inside.

I bought a piece of practice glass and did two repairs trying to replicate this condition but couldn't. I've experienced this on new and old vehicles.

need some help on this one

thank
Roger
