1) with
THIS
Making the cracks bigger by cutting in de plastic bumper besides the cracks making a V-shape incision. Then melting the cracks with a soldering iron, melt the plastic rods inside the cracks and hope for the best. Afterwards I put some plastic filler over the plastic melted inside the cracks. The first time I used
THIS but from a different brand but I din't work as it should have.
This is a photo after the cracks were repaired on the inside of the bumper. The black stuff is the plastic rods melted inside the cracks.
Put some plastic filler over the repaired plastic with the plastic rods.
The outside was and entirely other matter. I couldn't seem to get the cracks filled with plastic flex filler, so I started all over again (outside of the bumper) and this is what I did.
First attempt
Cracks were repaired on the inside of the bumper but not on the outside of the bumper, not yet.
Very first attempt with filler.
It doesn't show on the photo but you could clearly see the cracks coming through the primer/filler. So I had to start all over again and try something else.
Other thing I tried
I was guessing and didn't know what I was doing but I tried and it worked out just fine.
Sorry for the Dutch tekst but I did it to explain what was going on.
Also on the front side, I cut V-shape incission (sort off
) along the cracks.
Melted the plastic of the bumper and the plastic rods with a soldering bolt.
Sanded the plastic as good as possible which isn't easy.
Had to cut a piece of the bumper because it was always sticking out.
Also repaired a crack from 4 years ago which was very poorly repaired by a professional car body workshop.
I had to repair cracks he didn't repair 4 years ago.
Final result
2) I already put, locally, a primer/filler from Finixa on the bumper. I'm going to basecoat (with the correct colour) and clear coat it. I still haven't figured out how though. I don't have a descent spray gun and compressor. And, I have never used a spray gun to paint a part of a car.
I have googled to look up acryic enamel. I never heard of it. I don't know what kind of paint I should use. Although I'm against it, people say I should use solvent base paint instead of water based paint.From what I have just read on google, acrylic enamel is outdated and doesn't give the same result as basecoat/ clear coat.
