PUSH Install Gel vs. GDI
GDI is a popular ready-to-use slip solution in a lot of PPF shops. Here's the honest comparison for installers weighing a switch to a concentrate.
| Feature | PUSH | GDI |
|---|---|---|
| Format | Concentrate (mix on site) | Ready-to-use |
| Cost per gallon mixed | ~$0.42 | ~$1.10 |
| Shipping weight per gallon | Light (packet) | Heavy (liquid) |
| Slip on PPF | Tunable | Fixed |
| Tack break-down | Clean | Clean |
| Tint + PPF in one product | Yes (documented ratios) | PPF-focused |
| Stock footprint in the shop | Small (packets) | Large (jugs) |
| Fragrance | None | Mild |
The verdict
GDI is a fine ready-to-use option if you don't want to mix anything. PUSH wins on cost per gallon, shipping weight, shelf space, and works for both tint and PPF — so mixed shops cut their slip-solution spend roughly in half by switching.
