Here's a picture of a repair to a tackle bag I did a while back, using Aquasure as a cement. It's one of those stupidly designed ones with a diagonal seam across the surface which is normally dragged along the floor (opposite from the handle). It's not rocket science to realise just how vulnerable to wear this seam is. The same method can be used on oversuits
if they can be held flat.
1. Clean all components with a solvent cleaner thoroughly.
2. spread newspaper on the carpet before going any further and place the tacklebag / oversuit FLAT on it.
3. Apply Aquasure inside the grey "flap" (in this case) but not so much that it oozes out.
4. Apply Aquasure to the patch (in this case cut from an old PVC oversuit) and to the outside of the tacklebag.
5. Place a card or newspaper over the repair.
6. Place a big heavy book on the card.
7. Place loads of diving weights on the book to compress the whole assembly firmly.
8. Leave 24 hours at least, then remove card, book and weights.
9. Apply a protective bead of Aquasure on the remaining exposed stitching either side of the yellow patch.
10. Apply a bead of Aquasure around the edges of the patch so it doesn't catch and get pulled up in use.
The repair below has lasted for about 5 or 6 trips since. I often repair my PVC oversuits using a similar technique, usually with reasonable success.
You can also see that small blobs of Aquasure have also been used to repair umpteen minor blemishes elsewhere in the past; a stitch in time and all that . . .
Hope this helps.
