Currently have a 1992 Fiat Ducato Swift Capri 520 GXL. We have had this for about a year and it is our first motorhome. As seems usual reading a lot of the threads, we did not get her properly checked prior to buying. We have a couple of areas of damp and a couple of leaks in the wardrobe/toilet area. This is not bothering us too much, however would it be OK to just put new sealant over all the main seals without removing the old stuff or will this just cause us more problems in the future. Have spoken to our local dealer (Knowepark in Livington) and they are quoting about 3 to 4 thousand to get it fixed, saying that all the old sealant will have to be removed. We are planning to upgrade in a couple of years. Any help and advice would be most grateful.
