my 1980 dolphin does use the 1X2 strip you are asking about, as the framing. I am also replacing my ceiling panels with plastic panels instead of wood. I am also going to use a little of the same plastic paneling behind the stovetop area, as a splash guard,where there is currently wallpaper. Hi. Saw this post and I am also replaceing the rot in my 1986 Sunrader,headliner/wall. Would like to know more about the plastic panels Was going to use the 1/8 door skins!Hope I didn"t interupt.Don C

Dave I have used the core material that you are looking at,and it is just the core (center)of a composit. You will need to have skins(fiberglass or wood)on the outsides of the core to give the core strength to do the job. I have a 86 sunrader at present and it is cored in the center and has fiberglass on the outsides making a sandwitch type construction. also the cost of the project would be outragious.Also most core material need to be vacuume bagged to bond the skins to the core.Hope this helps ,would be cheaper to buy a sunrader which is already cored..Useing these cores requires quite a bit of expertise and the learning curve is expensive. Hope this helps. Don
