Prout Owners Association

Good morning all. The windows on my '82 Sirocco are heavily crazed, and need replacing.
Not sure if all Prout windows are like mine, but the perspex is bolted to the outside of the coach roof, with an edge chamfer on the mating surface, for the application of sealant.
Does anyone know of a Company who makes and fits this kind of window?
Regards,

you can do it yourself,buy lexan or simular,closed celrubber from 5mm(non sticking) and good sealing/kit
first cean the surface,then a good amount kit,then the celrubber in a stroke fron 4/5cm,the again good amount Kit and alast the windows,
we did also again with screws
