[Spridgets] Seam sealer

[Timothy H. Collins]

I want to put seam sealer on my Sprite soon, but am wondering when it 
should go on. I have sandblasted the body and then gave it a coat of 
etching primer. The plan is to send it off to a body shop for base / 
clear top coats. I assume the body shop will spray a primer first.

Should I put seam sealer on before the body shop primer coat or wait 
until the shop has put on their primer coat?
Thanks
