i have a small hole at the bottom of the a pillar right at the back of the guards (where arrow points, hope whoevers ute pic i borrowed doesn't mind!)where it looks like a few panels join. Its just at start of the little lipped channel that the top of the guard sits in

It doesn't look like a rust hole and is on both sides, it looks like its just caused by panel alignment. Just wondering if this is common on 1200's, if its a necessary hole for drainage or whether i should just fill it with sealant and paint over it?? thanks
