Here's a real (non-prototype) filter that I just completed...using my last stencil,
converting an NOS AC Delco PF-25 to assembly line style. Still waiting on my printer to produce more stencils!
NOS PF-25 Paint Removal (aircraft paint stripper)
Ready for base coat and stenciling.
Base coat - first of 3 coats applied. Base coat paint is infrared cured between coats then left overnight to cure.
Stencil is applied, top layer of stencil film is peeled away revealing the working stencil layer, then the body of the filter is taped off ready for black paint layer. Stencil indexes against the top rim of the filter.
Black (semi-gloss) paint applied
Completed PF-25 transformation (minus the seal)
