I have done a lot of grain filler threads but I want Fernando to see his baby in process.
First let me say that there is not only one way to fill grain, this is the way I fill grain to reproduce the look of a 1954 Strat. I love the way the grain really gets highlighted by doing it this way.
So here are the steps I take to get it ready.
1. Sand with 320.
2. Wipe it down with acetone. The reason I do this is it shows me any small scratches or dings I have missed during the first sanding. I'll sand anything I did not see at this point with 320 again. If there are any dings I'll steam them up with a wet rag and soldering iron and then sand that back. It also will clean any gunk that is on the surface like the glue residue from the little sticker that is attached when it is shipped.
3. The last step before starting to fill it is to blow the sanding dust out of the grain. It is very important to use a air gun and blow all the sanding dust out of the grain.
4. I use Jasco oil base paste wood filler because I have found it to be the best at giving me the correct color.
5. I brush the filler on with a paint brush going with the grain. I needed some sunshine so I did it out in the back yard today. I'm getting low on vitamin D. :laughing7:
I do the whole back first and roll over on the edges.
6. I use burlap that I buy at the fabric store and I wipe the filler off across the grain once it has flashed off.
7. I do the front just like the back and once it is cleaned off I do the sides.
8. After all the filler is off I take tooth picks and clear any excess filler out of all the screw hole and then blow them out with the air gun.
9. Now it is ready to hang for a few days so the filler can shrink and then I'll do a wash coat of finish and fill it again. I'll post pictures of that step in a couple of days but for now this is what it looks like.
