sealer

Hello,

I've used it several times with no problem under poly. Make sure you put on several coats lightly sanding between coats. Buy the least expensive can you can find. I think I paid $2.00 for a large can at Walmart. You can also use Minwax sanding sealer of their spray lacquer. This stuff stinks like a good lacquer should.

I've seen several post that they do not ues a sealer, but I've have numerious problems not using it.

The problem with hair spray is it's mostly water and will raise the grain with every coat weather you sand it or not because it's water soluble. Deft sanding sealer works great, it's laquer so dries fast and sands easily with 400 grit. If I'm covering it's gonna get the laquer treatment and the covering sticks better. Don't take my word on it do your own test with some scraps and you will find the covering on un treated balsa will pull right off. Leroy
