Bondo® bumper repair adhesive kit is so easy-to-use, you can do it yourself and get professional looking results. The kit includes a single use syringe dispenser containing equal parts epoxy and hardener. Just press down on the plunger and the two part material mixes accurately as it dispenses from the syringe-no premixing required. This epoxy applies directly to rips and cracks in flexible auto-parts such as bumpers and bumper covers, with a working time of only 6 min for fast, easy repair and restoration. For filling larger holes, the versatile formula works as a filler, simply apply the paste into the hole using the included reinforced mesh and spreader. The material forms durable, permanent repairs that hold up to sanding and readily accept paint. Yet it stays flexible, matching the original functionality of bumpers and other semi-rigid plastic auto panels.
