We ran both sprays on the same M3 Competition simultaneously — HydroSpeed on the driver side, HydroCharge Plus on the passenger side. Same application method, same wash schedule, same parking conditions. At six weeks HydroSpeed was still sheeting water cleanly. HydroCharge showed early degradation in the bead pattern. At eight weeks HydroSpeed was the clear winner. The four-dollar price difference doesn't explain the performance gap but HydroSpeed is still the right call.

Frequently Asked Questions
Is HydroSpeed or HydroCharge Plus better?
HydroSpeed. Better beading durability at 6 weeks in CGR testing, lower price, no meaningful difference in application ease. HydroCharge Plus is a line extension that doesn't justify the price increase.
How long does Chemical Guys HydroSpeed actually last?
Meaningful hydrophobics in real Wisconsin driving conditions last 4-6 weeks. The official 6-month claim requires ideal wash conditions and no stripping soaps. Budget for monthly reapplication on an uncoated car.
Can I use HydroSpeed on a car that already has ceramic coating?
Yes — and this is its best use case. Apply it as a maintenance topper after washing a coated car to refresh the hydrophobics between full detail sessions. It layers well over CQuartz.
