I wouldnt drill the rubber tire itself. Only the inside of the rim. Less likely to get in their IMO. If something goes in, no matter where the hole is, the object is going to have a hard time getting back out. Especially if it is FORCED in there to begin with. Which I think is way more likely to happen on the ouside of the tire. Landing from jumps, laying heavy into the turns and 'lighting them up' would all be pretty good opportunities for debris to get in. From the outside.
The plastic of the rim is thicker, stronger and hard to force things into. If you run dish style rims, your chances are even less of debris being forced in. But it still wont be easy, even with spoke rims. Yeah, I've caked up the insides with mud, but dont recall anything other than some 'dust' on the inside of my foams where the hole was when replacing the rubber or foam.
As for the CA I use, ZAP, ZAP Odorless, Fields Hobby Brand and Proline are all the names I have/use. As for weights, I have a variety of thick, medium and thin. Most of the time I use thin weights for the initial glueing and then follow up with medium/heavy to fill the gaps. Usually only get big gaps on the maxx and savage tires. Sometimes a buggy tire If I dont trim the foams good enough.
I'm just hard on my poop. The whole go big or go home line suits me well.
