paint prep

I'm having trouble with the grain of block coming up after the primer sealer coat.
Is there a sealer that stops this? IF so is it used before or after the primer?
Any and all suggestions would be highly appreciated.

thanx g.o.racing

We use Kilz Original Oil-Base primer on our cars. Typically the first coat of primer always raises some of the wood grain. I sand the entire car lightly with 300 grit sand paper then apply a second coat of Kilz after drying for 24 hours. Then repeat with a third primer coat if necessary. Finish is oil based enamel, not lacquer, of latex (water based).

The biggest thing I can recommend is to sand the wood finer. I dont know what you are currently sanding with but I sand mine first with 150, then 240, 320, 600 then 800. It doesnt take much time at all and it is super smooth. The other thing I can recommend is to use some Automotive grade Waterborne primer. It dries super fast if you spray it, but you can also brush it on but it will take overnight to dry. The Dupont brand is ready to spray No reducing required. Once dry use some guide coat and sand with 600,all of which is dry sanding never wet. Once you have done that, you can paint it with what ever you want however you want and it will not have any wood grain what so ever and it will stay that way for a very long time!

Your best bet is to use oil base primer to reduce the grain from standing up. You can use almost anything though but you will need to sand between coats to smooth the finish. I use Duplicolor-Color primer filler and it will fill small imperfections, just dry sand with 400 grit or finer between coats and before your color coat.

My son & I like the Duplicolor paints because they are available at most auto parts stores and are easy to apply. Aaron (my son) painted his car last year with them and we were sold on them after experiencing issues with other brands.

krylon primer with sanding in between coats can be made to shine before color coats. Wet/dry 3200 grit will polish it nicely.

I recommend using a marker. 60% of the time, it works everytime.
