Any need to use gasket dressing on thermostat or water pump gasket?

I bought all new spring clamps. They are considered one use clamps. If you really must, you could reuse it, but I personally would not recommend it unless you have no choice (like you are stuck on the road and need to get to a garage).

FWIW, you don't have to use Porsche spring clamps. I bought all OE ones, but many use the standard hose clamps you can buy at any auto parts store.
