Water pump gasket is leaking. What's your favorite coolant leak sealer?

[BTR]

2000 Explorer XLT 2WD 4.0L SOHC JOB1. 5-Speed Automatic O/D 5R55E. Manufactured 09/99.

I replaced the OEM water pump with a GATES 43279. I used the Fel-Pro gasket from that came in the Fel-Pro TCS45986 gasket set. I have a very slow leak around one of the water pump bolts. Other than K-Seal, what's your favorite coolant leak sealer and why? Please advise. Many thanks!

@Turdle - Thanks! Also, if the gasket is leaking, other than K-Seal, what's your favorite coolant leak sealer (that I can pour in the radiator)?

K seal , only, last resort. Why not replace gasket?

@Turdle - I'm getting old. Because of this, repair jobs are getting harder and harder to do. I prefer saving money by doing things myself. Not sure how I'll proceed.
