    Marine Sealant

    As well as waterproofing, marine sealants are just as useful for insulation purposes, including stopping draughts and minimising engine noise. Adhesive sealant is an inexpensive but effective solution. On Mailspeed Marine we stock everything from silicone sealant to colored sealants. You may also be interested in our gelcoat and filler or epoxy and adhesives section.
