Default Replacing thermostat 88 Sierra

Hello and thanks for helping...
I recently replaced my thermostat on my 88 GMC K1500 Sierra. It has the 5.7 ltr motor, a pretty simple job. However, I now have a leak right at the gasket. I didn't use any type of gasket sealer. Should I have used a gasket sealer? It seems like I like to do my repair jobs twice, so I'm guess the answer will be yes. If the answer is yes, what type of gasket sealer is recommended? Thanks, Mike
