  • A: Hi jeff, To loosen seized parts, you should spray the oil on thoroughly and let it sit. For specific stubborn bolts, let the product sit for about 10 minutes was effective for removal. We do not know how big the plow is so we are unable to answer how many is needed.

Always like having a can of kroil oil around. The oil that creeps gets into where I want it but personally I think it is way overpriced.

Yes, I recommend this product.
