I'm in the process of finishing the SEMROC Orbital Transport and need some recommendations on primers or sealers.

I just ran dry with the final coat 1/2 done
I'll bite the bullet to finish this build, but I be at Depot on the weekend and p/u a can of Rustolem (no more K-mart in Canada) for the Javelin I'm starting on next week...

Much appreciated

I too use Rust-0-leum Auto sandable primer and think it works great. I find it at Lowe's and Home Depot. It dries quickly and is easy to sand either wet or dry.

Well, for a sandable primer it's hard to beat the Walmart Colorplace 96 cents a can stuff. The red primer has a little more solids for filling minor imperfections, and the gray sands silky smooth for a great finish. I usually just use the gray and it works great.

Can't beat the price either... OL JR

Walmart Colorplace Grey is what I've been using lately as well, can't beat the price. Fills well and sands very well.

For balsa fins I use Behlen's sanding sealer which is available in spray cans at a woodworker's supply store like Woodcraft. It fills the grain faster than the automotive primer and can be sanded in as little as 30 minutes in dry conditions. It also does not fill the sandpaper as bad as primer. Once the grain is filled, I switch to the automotive spot filling sandable primer. Since these are two different products (although both are lacquers) I try to let the sanding sealer dry at least 24 hours before the first coat of primer. I've also used Rustoleum primer over the sealer.

Recommend Rustoleum automotive grey primer as several others said. Dries quickly and easily wetsands with 220 grit to a smooth finish.
