I do. The kit I got had enough to do all the plastics covers with a few spares. A nice cheap and easy mod that looks great. I've even seen coloured versions of the washer / bolt, nice if you are matching hoses or other items.
I'd post a photo except the plastic covers aren't currently on the car.

 

I bought this kit from TT Stuff. It was made by 42 Draft Designs. I'm very happy with the results. Unfortunately, I couldn't find them for sale online; I think they may have discontinued them.

 

Yes i fitted one off the cokbot kits looks good was about 15 pounds

 

Yep, fitted a kit when I replaced my front bumper after an unfortunate badger incident.
However I have a set of these for the battery cover.
Perhaps not as pretty, but much easier to access if you need a top-up charge.

 

+1 for Cookbots dress up kit

Agreed,i was toying with the idea off the wing bolts aswell.

 

All above kits looks nice. Very cheap dress up to make the engine bay look much better and practical too. I finished off my dress up kit today and if I were buying a car, I think I would consider that the seller was an enthusiast seeing the panel bolts being in steel instead of the plastic tabs. I saw a TT engine oil filler cap once, that would look nice probably but maybe best to leave as standard filler cap. Kevin

Many use 911 coolant and oil caps - I have both in that pic. Some also use R8 caps but they need adjusting/modifying

 

Hi, Forge oil & coolant caps look much nicer if you can find them at a reasonable price.
