I'm replacing my front spar on my project. Taking the hysol off is time consuming, but making progress.
My question is, can you put a new mixture of hysol over old cured hysol? OR do I need to remove every little bit of the old hysol. I'm only concerned with hysol on wood. I'm able to remove 95% free the ribs from the spar, but if there's any left, do I need to go back remove any remaining on the wood, or will it bond ok?
Thanks
Brian
