Guys,


Have made all the sections of my WMBC Police Launch. and now I have to prep for painting


Should I apply filler first, sand down and then apply sanding sealer or vice versa


On the matter of sanding sealer, it this the best practice or is there a better procedure.


Regards


Richie

hi there


General practice for myself is - to apply the filler and sand smooth - then apply the sand n sealer.   I then rub the sand n sealer back, looking for any places that may have been missed with the filler.   Then a 2nd and 3rd coat, rubbing down in between of sand n sealer.   I am unsure what sand n sealer you have been using - I use Deluxe Materials Sand'n'seal.   The advantage of using this is you can wash your brushes in warm soapy watter afterwards.


On my latest model, working purely in balsa wood, I have been using Deluxe Materials Model Lite lightweight filler. 


Just as a side note, our late great Dave Milbourn did an article on finishing models.    I will find the link for you, and put it on.   I think it may be on the plan for beginners Swordsman.

Hi, interesting.  I am in the painting stage of a model of Lilka an old boat kit from Poland.  There is a balsa roof and the sanding to shape is easy then I used thinned varnish a couple of times which stiffens the inevitable sticking up balsa wood filaments.  I then mixed up some filler and spread this where needed.  Then more varnish.

The filler pack I had by me had a white filler and a white hardener!  Crazy idea as you would never know if it was adequately mixed.  To overcome this I squirt out the hardener and then a dab of any colour enamel and mix them and then mix with the filler.  Easy to see if it has mixed up correctly.

Then sanding with 600 grade wet & dry repeat again and then painted with white Humbrol enamel.  This was done 3 times in all with the wet & dry inbetween.  The last coat was a Halfords acrylic Applance White spray and it came up with quite a good finish.

So substituting yacht varnish for dope works fine and I know I can spray acrylic on as a finish.  I find buying relatively small amounts of varnish OK as otherwaise eventually there is a hardened and unusable inch of varnish in the bottom of the tin.
I have found the Yacht varnish on sale in Poundland very good, I invested in 4 tins (125ml) when the prices were a pound, but things move on!
