John Dean Posted May 25, 2013 Share Posted May 25, 2013 I'm just part way through spraying my Super Star finished in the traditional way with sanding sealer, dope and tissue followed by cellulose primer but it occurs to me do I really need to use the tissue when the balsa is perfectly smooth and sealed? Anybody have experience of finishing a nodel this way? Quote Link to comment Share on other sites More sharing options...
Stevo Posted May 25, 2013 Share Posted May 25, 2013 If you are covering the balsa in tissue/dope, then that will strengthen it and no cracks will show through if they occur. No matter how well it is sealed and primed, the grain always shows through. Ive done a hollow hull speedboat like this and it has survived years and shows no sign of cracking. What is your planned finish? Paint will add quite a lot of weight though!!! Quote Link to comment Share on other sites More sharing options...
