Spackling ok to fill small gaps?
Hello,
I am working on my Top Flite Giant P-51 and I have been using spackling to fill small low spots, dents, and gaps before I fiberglass. I am going to use Deft Laquer sanding sealer to seal the wood before using waterbased polyurethane to glass. Will the sanding sealer react with the spackling causing it too wipe off, or will it be okay to use together? What do most of you guys use? I was thinking about wood filler but I didn't have any and didn't think too much about it until now. I am going to be using spot putty filler after glassing. Thanks,
Shannon

I use the light weight spackling exclusively. And after sanding if you'd like it a bit stiffer hit it with some ca. Check out my gallery, everyone of them are finished with the spackling.
Also if you have a joint in the sheeting not quite tight you can fill it with the spackling, let dry, sand , ca it, and then it is a solid joint.

Before filling any small dents and dings try getting them damp and then steam them out with a Monokote iron. You will be surprised how well it works. Like Ace said, you will want to seal the spackle with CA or my choice would be to wipe a thin coat of finishing epoxy. Apply the lacquer very thinly and about 3 coats. Use as little of the poly as you possibly can, after the glass is saturated remove as much of the poly as you can with paper towels. It's also best to do it with ambient temp of 70 or better. After it's dried for a couple days carefully sand smooth. You can then fill the weave with more poly with some baby powder, try to find the unscented type.

Thank you very much everyone for the input, I will continue as I find time and seal before laquer. I love the ability to ask questions (via the website forum) to get a lot of the dumb questions/experimenting out of the way. I'm time limited, but enjoy working on my project in the garage. I'm going to take a week off next week to get my project looking more like a plane. Thanks again!

Can you elaborate on your comment about sealing before lacquer ?

I made a mistake when I typed that. I meant to say sealing with lacquer before fiberglassing with the waterbased polyurethane. I am going to experiment practically step by step from Tom Pierce's website. This is my first attempt at doing any kind of finishing/fiberglassing work, therefore I following his guidance to a Tee.
