Snake oil, repairs in a bottle, hope in a bottle, take your choice but there is only one way to permanently fix a bad head gasket. Remember, "If it sounds too good to be true, it probably is".

What are your thoughts about this product??? Has anyone used it on NorthStars???
Check my posts in the Seville/Eldorado forum in the thread labeled Bars Leak headgasket. I recently used Thermagasket and to this point all is well. My headgasket leak was very minor, though.

I spoke with the foks at stealseal, and they were friendly, but basically said their product is a 50/50 proposition on Northstars and has better success rates with cast iron blocks and heads. If you use this product, they recommend going to the green siliccated coolant instead of Dexcool upon refilling.
