That's pretty cool. :thumbsup:
Well look at it this way... No matter what it won't last forever. No art ever does. Especially painted works, and especially when it gets put to use. Your idea of logging all the possible ways to extend its life period is great & that is what should be done and focused on. When it gets scratched up and worn simply have her paint another piece on it for you... and the cycle continues. Your board would be like a live canvas that you shred giant mountains with!!! but at the same time it is also an experiment for learning how to go about preserving personalized ideas and statements on your vessel. So far I think the clear coat is enough, maybe work several layers over a weeks period to thicken it...It was done with acrylics and painted with a brush....well a bunch of brushes of varying sizes....I am art speak retarded so yeah.
The process was:
1. Sand down topsheet to make it rough
2. Give wife idea
3. Get annoyed with artist taking too long
4. Wife decides it is time
5. She grabs her stuff and paints with acrylics for 2.5 hours.
6. tells me she is done and I need to put on a varnish
7. Get spray clearcoat
8. Put on clearcoat and get worried it wont work well enough
9. Post to forum
