have a 3 inch crack in an ocean rodeo mako 140. Depth wise it is about 1/16 - 1/8 of an inch. What is the best way to fix this? ive used ding stik before on windsurf boards, but they dont flex much. I tried using something called "peel and patch" which is an epoxy fiberglass patch. they wont stick to the board.

Im looking for solutions that are the
1) easiest?
or
2) most durable?

Been there done that with the Mako.

Repairable with good quality fiberglass and epoxy resin. Clean and dry very well. Sand 2~3 inches all around the crack, apply couple of layers of fiberglass, cover with food wrap PE foil and apply a few Kg of weight (bag of sand works well) with adequate support on the other side to make sure the shape of board is unchanged. Wait 24 hours, ride at least several more months before new crack reappears (maybe longer if you are careful!)

I'd like to know if this is a 2011-2012 model or earlier. OR customer support was great but I was cracking Makos faster than they could replace them (2009 model), then they moved to wood core in 2011, if wood holds up better I may give it another go :thumb:

Also, you could buy a piece of Peel Ply on Ebay instead of the PE, you press it over the glass and resin, then remove it after cure.
What about topcoating? Do you use a gel coat over the repair?

I bought the board used and the seller lied about the condition. The crack looks like it is an impact crack from hitting something. It is a 2010 model, although it looks like the core might be wood (I didnt use a grinder or anything to get to the core.

Are all epoxies the same? I was looking at these because the ease of dispensing.

Some complaints about it not being waterproof, although it isnt clear if they improperly mixed. Specs say water resistant.

Like I mentioned in the post below "no mess no fuss" method would be a P-Tex candle as essentially you are trying to build back the plastic material (PET, Durasurf,UHMWPE) on the bottom of the board which 99% of modern TT's use today as a protective/abrasive layer.

The bottom of the board is not made fiber glass it's a plastic that encapsulates the inner layers and usually something that epoxy has a hard time bonding to without being treated. Now if you not going for looks the epoxy route might work but after a while it will start yellowing due to UV exposure and water will find a way into the core over time, you are dealing with a small area under constant flex. Try the P-Tex candle I bet it will work better, cheaper. Use it don't use it.....

I just used this on a board I just bought

http://www.westmarine.com/webapp/wcs/st ... &langId=-1

Clean and sand the gouge with 220 grit
cut a thin strip of this and stick it in the gouge
get a wider strip and cover the filled gouge
UV cure in the sun
sand it down with maybe a 120 at first and 220 grit sandpaper at the end

Not sure how it would work if the gouge was deep as the thing uses UV to cure. Maybe do one layer at a time.

Just did this today and it was really easy.
