Dave its actually nothing to do with the Paint, Water or Solvent, Blistering is perferation from behind !!

Not familier with the Primers MMC are using to base the Panels, so i am un able to comment

Paint Shop
Body shells are painted in a semi-clean environment using solvent based paint. Shells are dipped in chemical tanks to cleanse them of any oils picked up on the panels during their manufacture in Body Shop. Once bodies have been dipped and cleansed, they are then immersed in an anti-corrosion paint dip called ED (Electrocoat Dip). This 'dip' coats the entire body, both inside and outside, and is the first paint coating it will receive. Once the 'dipped' body has been stoved in the ED oven, the body progresses to the 'Sealing' Booth. In this booth, the body has its interior panel joints, floor, tailgate, hood and door edges sealed with a PVC based sealant, to prevent water ingress and corrosion as the car is driven on the road. Also within this zone, sound pads are added to the floor and boot to reduce road noise (standard practice in the motor industry). The next booth it enters is the 'Underbody' Booth. In this booth, similar to 'Sealing' Booth, the body's wheel arches are sealed using the same PVC based sealant. Robots then apply the underseal to the underfloor and wheel arches. Also robots are used to apply the SGC (Stone Guard Coat) layer to the sills: this coating is designed for abrasion resistance, i.e. preventing stone chips, scuffs, etc. From here, the body proceeds into the Undercoat Oven. The next zone is 'ED Sanding' booth where the body is inspected for any minor imperfections received in the ED Coat. The next zone is the 'Surfacer' Booth, where the body receives its second coat of paint, this being the Surfacer Coat, then into the Surfacer Oven. Next is 'Surfacer Sanding' Booth: the same as ED Sanding, this zone inspects the body for any imperfections picked up within the Surfacer coating. Next comes the 'Topcoat' Booth, where the body receives its final coats of paint, these being Topcoat and Clearcoat layers. After being stoved in the Topcoat oven, the body then enters the 'Touch-up' Booth where the body has its final inspection for any imperfections picked up in the Topcoat process. Once the body leaves here, it then moves on to the PBS (Painted Body Store) above Trim and Chassis to await the next step in the production process.
The processes a modern day mass producer would use, i doubt 'as a small number producer' Morgan will not have the ability to put this method into practice.
