Which farm trailer panel method should you choose?

Full panel repaint

Use the EP primer and PU 200-90 build where side panels or utility panels need a complete controlled colour finish.

Local exposed metal areas

Use EP primer only where the preparation exposes bare or prepared metal before topcoat.

Practical farm use

Mask moving hardware and service points carefully so the coating improves the panel without blocking daily trailer use.

Technical details

Mipa PU 200-90 is a fast drying 2K polyurethane acrylic topcoat for machinery and agricultural vehicle coating work.
Mipa PU 900-25 hardener and Mipa 2K Thinner are used in the PU 200-90 liquid topcoat stage.
Mipa EP 100-20 is the epoxy primer stage for prepared metal and other listed substrates.
Cleaning, sanding and dust removal must be completed before primer and topcoat are applied.

Practical suggestion

Farm trailers often look simple, but dirt hides around hinges, panel overlaps and side board edges. Clean those areas before sanding so contamination is not pushed into the coating surface.
