A few weeks ago, I fixed a bumper cover on my sister's LEASED Altima, trying to save her some cash. She backed into a pile of ice, cracking the bumper cover. Lord Fusor epoxy was recommended, and it worked just fine.
Apparently, my sister has a hard time judging using the back-up camera. She again backed into something, cracking the bumper cover in the same place. This time, I decided to plastic weld the crack. I forgot to take pics as I progressed, but will post some as I finish.
To make sure I had the right material for the weld, I called an old customer who owns a body shop, and asked if she had any late model broken Nissan covers, or even just a piece of one. She did, so I got a piece, sanded off the paint, and cut a few strips.
I removed all the epoxy, sanded all paint off about 3" in all directions and made sure I had a sufficient groove for the weld. I used aluminum tape on the outside to keep the pieces aligned, and welded the inside. I left the buildup intact until I had the outside welded. Then I used a course 2" disc to get close, followed by 80 grit, then 150 grit, feathering out the edges. I sprayed the inside of the cover with gray epoxy, so the repair is invisible. I used buff epoxy on the outside, which is where I left off, and will start taking pics tomorrow.

After spot priming the damaged area, the whole cover was scuffed with 320 and shot with white epoxy primer. While wet sanding the primer with P600, I found low spots in the damaged area. They were just small, very shallow depressions that could hardly be felt, but imperfections shouldn't be ignored. So, I sanded off the primer, and filled with Lord Fusor epoxy. the epoxy was sanded with P80, then P150, as per Fusor instructions.
When all edges were feathered, and the repair felt smooth, adhesion promoter was sprayed, followed by more epoxy primer. |
