I have built a few rmc cobras and i would recomend putting in the rubber gasket . I use self adhesive sela rubber from bunnings it comes in 3 grades of hardness i use the medium ands its dead easy to fit its an inch wide so i run to strips side by side on the wider chassis parts .
no glueing it takes about 1/2 an hour to fit it up.
Another tip for you on rmc is to trim all your edges before you fit the body i trim the wheel arches down to 10mm wide it still keeps the strength but allows more tyre clearance.
