We have a number of Spitfire Spade-grips that are in need of new covering. The plastic crinkle finish on the right hand side and the smoother covering on the left are cracking up and need replacing. Has anyone had any success with a representative usable coating? We have had prc/waxed string and neoprene/waxed string suggested and a commercial coating concern managed to give us a horrendous quote for doing it. I don’t think the “Knicker Elastic” quoted in the PL983 book is in the running to be honest!

Supermarine Aeroengineering in Stoke have developed a method of covering the grips thats looks exactly as per original, perhaps its worth speaking to them,see..

I use a fine twine as a basis……and then build up a thin layer of Metallic. I smooth it with my finger and then use a sharp side of a file to make multiple grooves – it is very hard and resistant…..Paul Cole (another Hurri nut) has done stuff too.
Early Dunlop grips used a thermoset bakelite covering which (I think) was created on a wax proof backing and then wrapped around the grip and sealed with a hot iron. Later grips put down a thin, fine (I mean Egyptian cotton fine) fabric first and then the thermoset type covering on top.
Many in service repairs (particularly later Spit grips where the tubes in the left hand side (as seen by pilot) move/flex and break the covering have string wrapped around and then secured in place with some kind of varnish (or for modern use painted on resin).
The best replica covering I have ever seen has been done by Roy Bonser.
Up to the Tornado GRI, Dunlop still used the same grip finish.

Epoxy
I have seen two part epoxy resin used for this in the past – built up rough to the required depth, a small file used for obtaining the surface finish required and then finished off with a suitable paint.

I have found the black fabric superior handle bar tape used by serious cyclists of yesteryear can be bound and built up to a very good substitute.
Must be the fabric tape, not the plastic.
