It is starting to show its age, and needs repainting; perhaps now is the
time to change the colour and blend in.

What paint should I use to cover the red - are there any special

Just don't use anything water based. Low vapour may be an advantage
indoors, but IMO it's solvent based all the way for outdoor jobs.
