Clear varnish or white glue mixed with water….
paint it on thinly, allow to dry and then paint on another layer until you have it at the hardness you require.
You could cover it with wheat paste and newspaper. When it dries you can paint it or
wrap it with tissue paper.
You could also cut another tube up the middle and coat the inside with glue and wrap it around the tube you are trying to strengthen.
