Gentlemen I have the 40-158 cabinet stripped, repaired and sanding sealer applied. Tomorrow I plan to apply the grain filler. I have a few questions since this is my first restoration.
1. Do I need to sand the sanding sealer prior to applying the grain filler, if yes what grit is proper?
2. Once the filler is finished (applied, removed and clean) do I spray it with sanding sealer again or go ahead and apply my toner right over the grain filler (once it is cured)?
3. Once I have the toner the way I want it, do I go ahead and spray the first coat of clear over the whole works and then do a wet sand followed up by any additional coats of clear?
4. Is there a estimated tack time between the toner coat and the clear lacquer coats. I realize temp and humidity will play into it, but I'm planning to wait for a perfect day to do the actual finish.

Thanks for any help!
