350 is too low to polymerize the fat and carbon.
Use less oil (wipe the surface until it looks bone dry) then try 475 - 500 For an hour.
Stovetop method works too.
My only advice is to sand or file down the rough edges on the handles.
It seems that Lodge has stoppEd doing a lot of finishing work on their cast iron and most new Lodge handles feel like grabbing a steak knife.
it is an easy 5 minute fix
I grill and smoke year round because I’m kinda weird about cook’ing meat inside.
that being said , I definitely stop taking photos of the cooks when the temps are cold
