Semroc Wac Corporal Build, Part 13, White Undercoat & Sanding


It never fails -

I think I've done a good job making smooth fillets. I think I've picked up all the excess glue before it has dried.
The first white undercoat usually brings attention to all the flaws.

On the left is an uneven glue fillet.
On the right is after careful sanding with some older 4000 grit. 
You can sand yellow wood glue.




A before and after of the flue fillets on the upper launch lug.

Sand under a bright light. Sanding dulls the gloss white. Low areas that need more sanding will still be glossy.


Here's a noticeable glue booger near the leading edge of a fin.
On the right is after sanding to surface. 

In 48 hours, another white undercoat and probably some more sanding.

  1. Hi Chris,
    So is yellow wood glue preferable to white wood glue in that it is easier to sand smooth?

    1. Hi Unknown,
      I've never compared sanding between white and yellow glues. I would think wood glue would be easier to sand. It seems to dry harder than white glue. When laminating wood you always seem to have some squeeze-out that needs to be sanded off.
