- Mach 1 72, 302, C4, restoration in progress
Hi guys,
I tried to search over the forum but cant find this thread there. I am in the process to finish my '72 and the front bumper repair started. The bumper was in seriously bad shape. The urethane cover had several heavy cracks about 1/4 -1/2 inch wide and also several hair line cracks all around. I have brushed the paint. I cut the urethane cover and remove metal bracket which was hit by some accident. I have to fabricate an weld apx. 1 ft of right side as it was completely rusty. This weekend, trial test the bumper on the car. It fits quite well. Now to the questions.
What adhesive to stick the urethane cover to the inner metal reinforcement. I feel a Polyurethane seam sealer might work. I tried its sticky to urethane used to bumper.
How to repair big and small crack. I intend to use PU sealer as well at least to fill heavy cracks. however this material is difficult to brush to complete, It has to be rather to cut with a blade.
I live in Europe and there is difficult to get any specific product for urethane bumper repair. Any idea what kind of stuff can work.
I see a 2k flexible epoxy in the market here. Its not so cheap but I can try. Ordering something from US is to wait 8 weeks for for delivery.
As next I plan to use several coats of epoxy primer, then base and clear coat. Not sure if any flexible agent is needed in the paint.
I want to duplicate original look of my car so a chrome bumper replacement is the last option of course.
Any help will be appreciated if somebody had an experience with repairs.
