Have no fear and take a risk. I had an old bench seat that was pretty shagged after years in the weather numerous pot plants decorating it. It resembled my neighbours but two slats had rotted through and a handle was falling off. Some slats in the back had rotted out. It’s was destined for the bin but I needed something to do so broke it down and replicated the rotten bits using opposite end pieces etc which I cut out of short sticks of pine I picked up from Bunnings. Some screws to replace the original dowels and glue. It firmed up good but the mix of timbers Kwila / merbau and pine didn’t Look great.
if you get this far forget the stains. PAINT.
Tools my trusty ozito 18volt drill and circular saw stainless screws and sellers exterior pva.
A good undercoat with British Paints water based 4in1primer sealer undercoat and then the magic happened bright orange Dulux water based enamel from the paint crew at Bunnings semi gloss gave a hive surface and the satin finish hid the imperfections from my wood work.
