One thing to keep in mind is the bead roller may stretch the metal as you work it. It may crown up in the direction of the bead. I've been able to flatten the sheet with just my hands and a hammer, but sometimes a shrinker was needed. For a larger piece like a trunk floor, you'd probably need a deep throat shrinker, Harbor Freight sells an OK one. Remember the old saying, "Work the metal, don't let it work you."
Yes, thanks. On almost every (stamped) replacement panel I've ever installed, you can "feel" the built up stresses in it; some worse than others.
How much work I have to do on it afterwards just remains to be seen, but at least I know not to expect miracles.
For the 318ti, I was ordering two (2) 4' x 4' sheets (20ga), until I got to the shipping calculater (metalsdepot.com) and it came back with $121.00!
I recalculated it ordering four (4) 2' x 4' sheets and the total freight was $16.00!
So, I just made $105.00 by (plug) welding a stepped seam across the width of the trunk! I figure it will add strength too! :wink:
