Jb Weld on aluminum intake

Disclaimer: I weld aluminum for a living, there are a hundred guys that use JB weld all over the place quite successfully. I would simply not use it as I have been "rewelding" JB weld repairs for about thirty years. Cheap repairs on aluminum aren't good and good repairs on aluminum aren't cheap. Not trying to start a turd storm here just explaining my point of view after trying to repair countless epic JB weld fails over the years. What typically I could weld in a few minutes had they just brought it in turns into a lengthy struggle as the JB weld does in fact bind to the material and depending on thickness is a real bugger to clean up to the point of actually welding. Think canoes and chainsaw parts here. A manifold may have enough thickness you could grind a pocket and be successful? I just would not. My apologies this got long winded.
