Is the tub (lower body) on a 2007 Max IV polyethylene? I have plenty of that. I found 2 holes in my tub, one where at one time, the tracks came off and ate a hole in the tub. Somebody tried to fix it but failed, then when I steamed the tub out today, I saw daylight through a dime size hole in the bottom. Guess I'll do a little plastic welding. I think I read somewhere that the tub material was polyethylene. Any body help me here?
HDPE
I was successful in welding up the hole in the bottom and a huge gash on the left rear where a track ate a hole in it. Had to scrape off a ton of JB plastic weld. I used my Polyethylene to weld it up and it did a good job! I cut a filler piece to fit in the gash, heated and bent it to form to the gash. I tacked it in using a soldering iron then used a heat gun with an attachment to melt the plastic and flow it over the wound. Used the gun to smooth out the plastic. Can't hardly tell that there was ever a hole! That was the first time I'd ever did plastic welding, I've welded alot of steel but never plastic. Now I dare to take Max in the water. The polyethylene I used was black 1/4", tuff stuff, you could beat it with a sledge hammer & it won't bust! Don't know it it was HDPE, MDPE, LDPE, or WHMU but it worked really well for a permanent repair.
Any before and after shots?
I should have taken pictures but I didn't think to. The gash was about 6 or 7 inches long and 1 inch wide at the widest point. I think it is a permanent repair, looks good. I didn't do anything on the inside of the tub, I'd have to pull the engine for that.
I'd imagine you started with something like thisQuote:

The exact same place! Your repair looks good. It's pretty easy to repair (if you can get to it) but it's very time consuming. Did you have a track come off or what caused your damage?
That way when I got it.
