✅ In Stock
Marcy QuickCure Rain Sensor Gel is the professional standard for bonding rain sensors to automotive glass. The 12ml QC12 is the multi-use size — enough for multiple sensor installations — with a sub-4-minute cure time that lets you complete the job and move on. Clean, odorless, and fully removable, QuickCure leaves no residue on the glass when the sensor is removed for warranty or replacement work.

Application
Apply a small amount of QuickCure gel to the rain sensor pad, position the sensor on the glass, and hold in place for 3–4 minutes until cured. Use the QCL leveler for hands-free positioning during the cure cycle. Use a fresh nozzle (QCN) for each session to prevent clogging between uses.
How much gel does one installation use?
A typical installation uses approximately 1–2ml of gel. The 12ml QC12 syringe provides roughly 6–12 applications depending on sensor size, making it the best value for shops doing multiple rain sensor installs.
How long does QuickCure gel take to cure?
QuickCure gels in under 4 minutes at room temperature. Avoid moving the sensor during the cure window — use the QCL leveler to hold the sensor in place hands-free if needed.
Can I remove the sensor after it's been bonded?
Yes. QuickCure is designed for clean removal — the gel peels away from the glass without leaving residue, making it safe for warranty replacements and sensor swaps. It is not a permanent adhesive.
What's the difference between QC12 and QC4?
QC12 is the 12ml multi-use size, suitable for shops or technicians doing multiple installations. QC4 is a 4ml single-use size, ideal for occasional use or keeping one in the toolkit as a backup. Both use the same formula.
How do I prevent the nozzle from clogging between uses?
Nozzle clogging occurs when residual gel cures in the tip between sessions. After each use, replace the nozzle cap immediately. If a nozzle clogs, replace it with a fresh nozzle from the QCN 10-pack rather than trying to clear it. Do not store the syringe with a clogged nozzle in place.
