What are you guys using for the metal filler when porting your TB?

Snuffles

I used JB weld.

Many people will shun you away from using it because it can break apart/dislodge from your TB and wind up in your intake.
There's also no proven gain using the filler over not using the filler.
However, many people have been running it for years with no problems.
It should hold fine if it's applied correctly.

I just did my first one with epoxy. I used sme super epoxy weld stuff and it's definitely not going anywhere. All I did was use my dremel to make some cuts and holes in that section and then the epoxy will take better hold in there. Don't know if it makes a difference but it does look better, which matters if I'm selling them.

mine is filled in, hasn't gone anywhere in 2 years. You just have to scuff up the area, then hit it with some type of cleaner/degreaser before you use the epoxy.

I know it's been proven to add little if any hp. But if you score the TB and clean it like Grimes and others have done, it should hold decently. I'm just curious what kind of stuff people are using.
