Hi John

I'd say seal the heater unit with silicone, if you use clear you'll barely see it. I wouldn't worry about fire protection, it won't get that hot on the bulkhead, however if you are really concerned Screwfix do a Fire Retardant silicone at £6.99/tube.

The only problem is sealing right at the back of the heater, as access is a bit restrictive. Perhaps you shouldn't use so much water when you're washing the car!

Hi Dave
Thanks for the reply - I'll try the silicone round the heater box - a job for the winter months!

I thought about using less water and then my wife said - what about sending it to the Dry Cleaners!!

Am I right in thinking that this problem is not uncommon on the TF?

Regards

I've never had the problem, but then I don't wash it more than a couple of times a year!
