I finally got motivated to repair the floor board that had been broken by someone using a jack before I bought the car.
I scraped off the undercoating, cleaned the area well with enamel thinner, sanded it with 36 grit paper, and installed 3 layers of fiberglass using SMC resin. It looks like it should keep the water out.
Next is to apply undercoating so it will blend in with the rest of the underside.
I also repaired a small crack in the rocker panel. Now I have to paint it and reinstall it.
No, I did not take any other pictures.
Basically, here is what I did.
1. Scrape off the old undercoating from the floor about 8 inches away from the crack, when possible. It was easier to scrape if I softened the undercoating with enamel thinner first.
2. Cleaned the area very well with enamel thinner to get all the undercoating off.
3. Sanded the area where the new glass was going with 36 grit sandpaper to roughen it up a bit.
4. Cleaned the area with enamel thinner again.
5. Put on rubber gloves.
6.Cut out 3 pieces of fiberglass mat. The smaller piece covered the broken area and about 2 inches out from it. The next one was larger, and the third was larger yet.
7. Using a brush, I applied resin to the area the first piece was going to cover.
8. Put the smallest piece in place and saturated it with resin, making sure it was pressed against the floor.
9. Did the same with the second piece, and then the third.
This gives me 3 layers where the cracks and hole were, and additional layers going up to 6 inches away from the crack for good strength and adhesion. Make sure you get the SMC resin and just not fiberglass resin. It is really not a hard job.
