My head gasket started leaking due to over heating. This happened two years ago. I put a can of this and antifreeze the leak stopped. This year I flushed the radiator and put a new can of bar leak and anti freeze and no problems. Doing a head gasket repair can be very costly so far this is working no losses of fluid and no more white smoke from exhaust. You still need to keep a close eye on fluids may work may not.

I was pretty skeptical at first. I work at a Vet's office and have found that A LOT of these products out there do not work through many clients who have tried them. But, I tried it out because some of our clients were saying that it was working for their dogs. They were so excited to find a product that actually worked! I had just had my dog under for some serious ear cleaning from a lot of wax stuck down right at the ear drum and I didn't want to put her back under anesthetic so soon. So, I tried this Tropiclean Fresh Breath Gel. I followed the instructions of putting the Gel over my dog's teeth in the evening and brushed them in the morning for 1 month as directed. The idea of this Gel is that it works with the saliva and helps to soften the tarter on the teeth so that in the morning you can brush a small layer of tarter off. It doesn't promise to take it completely off in 1 day or 1 week. They recommend you try this for at least 1 month every night and day. I found that it worked very well. I would put it on her teeth at night which made her produce a lot of saliva and she would lick a lot. After that, I did not allow her to drink any water (as directed) until the morning when I would then brush her teeth. After 1 month there was no plaque on her back teeth. That part was awesome! However, I found that it didn't really help too much with the front teeth. My theory on that is because they do not get as much saliva "action" around their front teeth as they do around their back teeth with which they do all their chewing with. So, the lower amount of saliva around the front of the mouth doesn't react as much with the gel to soften those teeth's accumulated tarter. Which is why I only gave it 4 stars instead of 5. But, I have found that this product does work! I continue to use it and I recommend this to anybody who wants to keep their dogs teeth clean. (Just as an FYI: Keeping your dogs teeth brushed and clean helps to prevent organ problems - especially heart problems. It's not just to protect against teeth issues or bad breath.)
