temporary rubber roof repair ideas? 95 Fleetwood Elkhorn 11X

There is an elastic paint, mainly used for basement walls. A guy built his own camper and used the paint as the exterior covering. Last word after a few trips was he was happy with it the only downside being it was a bit harder to clean. If you are interested and you can't find it, I can do some digging to try and find his post (may be on this site or the FB truck camper group).

But if it was me, I would just do the repair right the first time and be done with it.
