2How easy is it to apply?
Effortless to apply by the boat owner or professional applicator alike. There are no complex or dangerous primers and no tight timescales for over-coating. Prepare and apply quickly or slowly. The application instructions are straight forward to follow, thoroughly tested and by following the detailed advice, users will achieve the perfect protective coating.
3What will one kit cover?
The 200ml kit will treat nearly 1m2 / 10.75 ft2 of propeller and stern gear surfaces. This kit will cover and protect one propeller up to 3ft/915 mm diameter or two propellers up to 2ft /610mm in diameter.
4How long will it last?
Prop-Defender is effective and durable and should last a minimum of one season, probably longer. Prop-Defender does not wear out, its only enemy is damage or abrasion, it will not lose any of its properties if kept out of the water.
5Cost effective?
Due to its advanced technology it is probably the most economical system on the market. Prop-Defender is available direct to the customer. It will save fuel and improve efficiency and usually pays for itself in weeks or months.
6What can I use it on?
All underwater metals including propellers, rudders, shafts, bow and stern thrusters, trim tabs.
7How easy is it to remove?
Unlikely you will need to as it can be over-coated by itself. However if required apply one coat of our citrus FR1 removal gel. Wait for 30 minutes. The coating will crumble and be converted to powder, for safe and easy disposal.
