Sealing the backseat aluminum plate from the trunk area.

VERY NICE JOb.... Mopowers That looks sharp.... I am definitely going to have to look into some Urethane sealer or the likes as I would like to tell you I still had the factory wheel tubs but the truth is they are gone as well ... as I used a set of wheel tub s in a flat box. Summit wheel tub s in a box are really fun to put together as well. ...&^#@#%^&(((^&%$#$#$ Make you say bad words!!!!!! But once you figure out how to get the seam made plus some mig welding they turned out great as they even got welded to the body for additional strength as well.
I had liked the 3M undercoat spray bomb sold by my Auto paint store but trying to be mindful about anything flammable in the trunk area or otherwise. There has to be options for sure ...just need to beat the bushes.....
