I once replaced the rotten wooden side pillars at the front of a caravan, from inside without removing any of the aluminium sheeting. To sort of waterproof it, I used that polyurethane (I think...poly -something)) foam they use when fitting new window and door frames to buildings.

I made a mix of the foam with cheap cellulose thinner(gun wash). They were reluctant to mix together, but eventually I had a kind of goo. I primed the wood and aluminium with this, and then sprayed the foam in the general area and pushed the wood into place.

Halfway to Poland, I remembered that I had forgotten to put the screws back to hold the wood in place. I checked.......rock solid. Got home - 1200 miles some of which on bumpy roads - and checked again.....amazing. Who needs screws?

If it can perform this well fixing wood to aluminium, there must be numerous other applications!

Its amazing stuff the polyurethene expanding glue isn't it?

Its holding some of the wood together on the Trav
