Super mono x hull crack help needed

[ercapoccia]

Hi guys i need some help. Today my gf's SMX hits mine very hard.

I had an hole and a long crack on the bottom.




The upper and the bottom part of the hull are partially separated.




How can i fix it?
I can mix some red ABS with acetone or mek to close the hole, but i'm a bit worried about the crack on the bottom.

I have Tamiya Extra thin cement but i'll probably buy some Tamiya ABS cement, it should work to glue together the upper and bottom parts of the hull.

I just did a similar repair on the Barbwire (same boat pretty much). I used loctite 5 min epoxy from home depot. A good coating brushed in over the cracked areas. First I carefully pushed out any plastic that was pushed in. Used a long flat head screw driver from inside. Then wrapped some sandpaper around a stick and sanded defect areas. Then cleaned with denatured alcohol and finally applied epoxy. Haven't tested in water but seems very strong.

Thanks for your support. I melted some abs with acetone, i pushed back in place the dent and i filled the crack with it, both side. I did three layers and the all the leaking are gone, but the part that was pushed in still flex. I'll do some other layer just to be sure. I'll probably need some epoxy to make it harder.

Yep, That's why I went with epoxy. Good luck with it

After many layer of melted abs the hull is very solid, probably harderd than new because now the plastic is thicker. I had just to wait longer between each layer.

I quite appy with the final result, not a perfect finish but i'm pretty happy with it. It my first ever abs repairing project.

This is how it looks after some light 400 and 600 wet sanding. I don't care much about esthetic i just wanted a tough hull.



Inside the plastic is very thick, it seems rock solid.



I covered all the bottom of hull with a trasparent plastic spray film
