Seam Sealer

[bigdaves12]

Hi all, just wondering if anyone has tried the brush on seam sealer cos I think its absolutely crap. Anyone had any experience with it? Also does anyone know if there is seam sealer in the form similar to silicone tube that you put in the sealent guns?

EDIT: Just googled it and found loads of gun type contraptions. Going to try one out. Any advice is welcome!
