Was after a bit of advice on how to fix a couple of damaged slalom fins. Just the usual nicks and scrapes from ploughing through sand banks and our lovely steps at Manly.

Do you try and simply sand them out, or should you try and fill them with something first to retain the original shape

Its a sad sign of the current wind conditions when this is what I am reduced to doing on my weekends.

You should stop before you hit the lovely steps at Manly.

we need to pump some finer sand onto that sandbank. 200 grit or finer.

Btw. where do you guys buy epoxy resin and fibreglass?

guys when you are buying epoxy, make sure you ask few questions. Epoxy is a different beast to polyester resin which requires an exothermic reaction created by mixing the two parts together. Epoxy's chemical reaction is not exothermic so requires a certain tempreture in the atmosphere to react. Different epoxy systems require different temps., some as high as 80 degress C. Check it out before you buy.

Also if you are going to mix a filler in to the mix, make sure you understand the different types out there. There are types out there that are for filling and are easy to sand and there are types, (which have a colloidal silica in them) which are for structural/glueing applications and are a bitch to sand.

Richie, your a genius! I will simply do a thick build up of expoxy and then run through the sandband at full speed until it is back to the original foil. You must have 2 brains in your head.
