Just wanted to post a positive experience I just had with Formula Guard. The shop that works on my boat is an independent two man operation who has worked on all my boats for years. My trim gauge was stuck in the up position all last year and I wanted it fixed, He told me the total cost would be about $400 because the sending unit was bad so that was what I was looking at for parts and labor. I asked him to call Formula Guard to see if they would cover the repair with him doing it and what do you know. The owner of the shop said it could not have been any easier for him to get the approval he needed and guess what...my gauge works again. Thanks Formula Guard!
