Do I need to prime finished wood before painting? Applying oil-based or shellac primer is a required step when painting over stained wood. One advantage to using a shellac primer is that it will be easier to paint over with a latex paint. If you use an oil-based primer, you'll have to rough up the surface of the primer so the latex paint adheres better.

Is it better to paint or stain pine wood? However, if you do need to paint or stain it a different color, you should choose darker paints and stains.

What is the best paint to use on wood? Unfinished Wood Water-based latex paint with a gloss or semi-gloss sheen works best for furniture that gets a lot of use. It creates an easy-to-clean surface that holds up well. For purely decorative furniture, opt for latex paint with a flat finish. How many coats of primer do I need on wood? On Bare Wood A traditional hour oil-based primer will take one to two coats.

The newer oil and latex primers will also take two coats for an effective seal.

The car we made wasn't great, but we learned a few "what not to do" things for next year. The car is about to be weighed and impounded. Last night, I put the wheels on. I was really disappointed. The big problem is that the car pulls sharply to the left. In fact, when pushed i. I had put glue in the axle slots before putting the axles in, so I didn't want to mess things up worse by removing the axles.

I tried pushing the front wheels a bit so as to bend the front axles to straighten the car out, and that may have helped a bit. What is the best way to assure straight alignment next year? And any suggested alignment fixes for this year? I don't want to tear the axles out. The other issue is wheel spin. I doubt ours spin for much more than 10 seconds. But given how much research I did on doing things right, I wish we'd attained better results.

If your rules require you to use the BSA slots, drill pilot holes in the slots to guide the axle as you insert it. After you're done, you can shape it any way you want, and your axle slots will be true to the now nonexistant sides of the block. I'm not sure I have a good fix in mind for this year's axle problem.

Maybe you could use a drill press with the bottom of the car clamped to a 90 degree fence of some sort. That might work if the bottom were still flat, but you'd be risking some pretty bad toe-in and toe-out if the sides of the car aren't square any more. Good luck, Marcus Show Quoted Text. Reply to Marcus Harton. When my kid was in the pinewood derby, the "axles" were nails. We chucked the point of the nail in an electric drill and spun it against a very fine file to smooth the shank where the wheel spins.
