New conv top, any maintenance tips?

[spinedoc]

I am getting a new top for my 1996 SL500 and was just wondering if there was any maintenance things I should look at while it is being done? Should I worry about waterproofing the top at all? I have obtained the top from GAHH and it is a German sonneland top.

Also has anyone ever had trouble with the rear hatch not closing? When I close the top the top part engages the front windshield pillar fine, but then stalls right before the rear hatch closes, I can get it to work if I slightly toggle the top up and down, but usually not in one continuous motion. I do hear the top locks click into place.

Thanks much.
