Randy.
Just as an example, although not cheap, I purchased a Supertex Indoor car cover.
I purchased it from Hamilton Classic Ltd at a Club Lotus Donington Show. Being a Club Lotus member I got a 10% discount, so cost me less than ?100. It is made from a very breathable, dust proof material with a soft fleece lining, so protects knocks and potential scratches.
If you are a Club Lotus member, you can purchase it from Club HQ. It?s listed on page 9 of the July 2016 Club Lotus News
For a +2, the size is ?SL? and current cost is ?99.00, with ?11.00 for delivery.
I have used it on my +2 since October 2011, as I have almost finished a complete nuts and bolt restoration.
So usage of almost 5 years and I can confirm I have not had any paint work issues. The car was completely stripped and resprayed and the finished paintwork left for 4 months, before the cover was used.
The photo shows the cover fitted, ignore the re carpeted boot rear panel, as this photo has already been resized to enable me to upload it.
