Repair broken spring wheel well damage (crappy trip)

We are very lucky indeed, thanks for all the posts.

I have 2 new tires on order and the spring dealer says he can only get 6 leaf 3,000 lbs springs. So that's what we are going with. Originals were 4 leaf 2,200 lbs springs.

Tomorrow I am heading to the local supply store to get some aluminum and asphalt coating.

Thanks for verifying my ideas to coat and seal it up
