I've bought several attachments from EA. Recently I had a situation in which I needed to take care of a leak on the dive case on a rototiller I bought from them*. I had been referred to contact a certain person and when I got someone on the line it was Ted! Really threw me off: my brain knew the voice, but it wasn't ready to associate it as Ted's. Anyway, Ted was willing to order me a new gasket (as I was looking to do) but said that I could very likely just reseal using RTV. As the original gasket wasn't torn I decided to try what Ted suggested: he even told me to just slightly snug things and allow the sealer to set up a bit and then after a while tighten fully. I don't normally endorse businesses or products, but EA is a case where I have no compunction to doing so.
*Wouldn't have had a leak if FedEx hadn't mishandled the rototiller! (it's a long story, but I wasn't able to check for damage when I picked it up- oh, and EA got me a new part that they weren't obligated to do) Friends don't let friends use FedEx! (I'm That pissed at FedEx over this!)
