Question Water Pump Repair - Did I mess this up???

I discovered the water pump leak a couple months ago and decided to venture on my own to fix it since it was out of warranty. I ordered all the parts and was finally able to pull it apart on Friday. I replaced all the o-rings, the mechanical seal and the oil seal.

I had a bit of trouble getting the mechanical seal in place, but finally got it thanks to a C clamp for a press.

I buttoned everything up, torqued to specs and ran through 3 heat cycles. I drove it last night and again this morning and it does not appear to be leaking

Here's my concern though, in the service manual it states to apply high temp grease to the oil seal. It didn't specify where though. I applied it to the underside of the seal thinking that it would seal the gap between the mech seal and the oil seal.

After I was done, I read on here that space is to allow fluid that breaches either the mech or oil seals to seep out of the weep hole so that cross contamination wouldn't happen.

After hearing that, realizing I probably blocked off that gap with high temp grease, I'm concerned that if the seals develop a leak (or maybe leak right now) I wouldn't notice which could cause contamination and eventually damage either the engine or cooling system.

After looking around down there after riding it and feeling the water pump, it doesn't feel at all like it's leaking. But...it does feel ever so slightly greasy But I may just be seeing/feeling things and may be paranoid.

So...is my concern warranted enough to re-order parts and re-do everything without the high temp grease in that gap? Or do you think I'm off my rocker and I'm fine leaving it as is?

I think you're fine. Grease will get washed out by any leak and allow its normal path.
I did remove the impeller, clean the little amount of wear residue on the seal, added a thin film of synthetic grease on exposed seal lips, and also on the cover seal when I flushed it out for new coolant. I also cleaned out peeling paint overspray in the cooling passage behind impeller and thermostat.
