Sourcing Pre-Made Log Plugs to Hide Lag Bolts

I do not like the looks of the lag bolts showing in our beautiful new cedar log home. The only solution that I have thought of is cutting an appropriate sized dowel,etc. and filling. Do you know of any company that sells premade log plugs in different sizes. (There are many bolts!!) The only other solution that I have heard offered – if you don’t like your lag bolts is paint them.I would much prefer making the lag bolts disappear behing wood. Thanks much for any input. Carol
