These are rubber seals very similar to the Renault ones i used on my blue Elan,not spongey rubbish that Lotus used
The tricky part is finishing the top where it meets the hood,i cut it level with the screen then used a flat piece of the same type rubber and cut out the shape to fit,i then superglue gelled this in position and then sikaflexed it to the frame,after 10 mins i dabbed the sikaflex with a rag dipped in olive oil to flatten the sikaflex and blend it seamlessly into the seal,the end result being a fabulous improvement on the originals,perfectly waterproof as it meets beautifully with the glass and will still look new for many years,these seals are probably 20 years old already!.
Hopefully here is the pics,Jamie.
