Thanks guys. After talking to a furniture ristorer yesterday, he said it would be ok, but..... Today before I got all your posts I applied two coats of filler primer, now need to rub back and fill some inperfections the I couldnt feel or see beforehand. I considered using a coat of clear first but on his advice I've just used a third of a tin of primer.
What do you think of a rub back fill where requied and a coat of clear then primer (both of which are same manufacture and claim compatablaty) then continue on as planned. The finish isn't to bad apart from showing the slight imperfections. I did consider oil as a finish but the wood had what appeared tobe a damp mark in it that I couldnt remove, solid colour appeared the best choice.
