I think a skateboard would be a little better, get some speed on the rocks and surf the riffles

I've got Coat-it under there now, durable but as you know not the greatest. Maybe the Coat-it just wasn't thick enough? 1 gallon was about 1/16 - 1/8 thick across the whole bottom. Gonna start fixing the cracks, just wondering if there is something better I havn't heard of. Maybe I should just avoid all those rocks?
