Had my 41 dipped.
Washed it down with water, dried it, and then sprayed it with DP 90 the same day I got it back. It sat for 4 years in primer in the garage while I finished the chassis, engine, and body work before I finally painted it. Been on the road now for about 6 years and has had no problems whatsoever with weeping. If it's done by an experienced dipper you shouldn't have problems.
