we use 3m flexable seam sealer at work i use it 1 or 2 days a week, it great stuff and will flex not crack like most 2 part systems........oyu may try this stuff out... thee are single part sealers also made by 3 m single part seam sealers will not require a gun to use, 3m makes one that you brush right out of the can, (with an acid brush) and my little tip on this kind is right before the sealer set up , have a latex glove on and dip you finger into thinner and rub gently over the sealer... it makes it smooth as glass ...and wont afeect the sealer.............hope this helps tony
