I have the se hatch with the typical rust blah blah blah.

I have a slight idea of how to repair it, but am not completely sure if it will work. I was thinking if i took off the spoiler, bondo'd the whole rusty area, and sanded it over and over again, that it would be as good as new. If anybody has any suggestions then it would be much appreciated.

lol, its funny you should be asking this question, because i've been doing this project for a couple a weeks now.

first off, i took the grinder to the rust spot(s), got rid of allof the rust. made a few holes, but nothing to worry about.

then i fiberglassed the holes, quite messy, then sanded it down

bondo, sand, bondo, sand, bondo sand. just untill your satisfied with the outcome.

then primer, sand, paint.

hope it helped. if not let me know and ill upload sum pics

That. Repeat: 1. Grind all the rust spots away. 2. Sand with 80grit sand paper to the area around the holes (top and bottom) to bare metal. 3. Use fiber glass resin and mat at the bottom of the holes, look does not matter here. Apply 2-3 layers. 4. Put bondo on top, sand with 80 grit, and repeat until satisfied. 5. Sand the surface with 220grit. 6 primer, use filler primer if you want a smoother surface, and self itching primer for rust prevention. 7. Sand 320 grit. 8. Paint.A sander will save you a lot of time.

I could be wrong on these steps, and materials selection. Body repair experts, please correct me. If you have access to a welder, weld those holes instead of fiber glass, they are much stronger. Also, go to local junk yard and see if they have wingless hatch there.
