Hey guys, not new to the hobby, but new to the forum. Just picking the hobby back up after about 5-10 years of not doing it. I've got a question about wet sanding after priming.
Little background on my painting procedure. I've always painted with rattle cans, and have had awesome luck with them, and my finishes always came out as smooth as glass (thanks Tamiya Spray Paints, lol.) Before, I never primed my bodies to be painted, always washed away the mold release agent and let them dry. While said parts were drying, my paint cans were in the hot summer sun warming up to raise the head pressure in the can, as well as warm the paint temps up inside, so they'd flow better.
This always yielded finishes like glass for me. Upon picking the hobby back up, I found this forum around Christmas time.
I noticed that almost all of you guys prime before color and have awesome results....so I figured what the heck, I'll try to see if it will make a difference on my first build back in the hobby.
My first model back into the hobby is a Tamiya Mazda RX-7 Efini.
I've sanded down all the mold lines, scribed all the panel lines, panel washed them, and filled in some sunken areas on the spoiler with some Tamiya White putty. After that, here is my wet sanding procedure ...600 grit (for the putty areas), 800 grit, 1000 grit, 1500 grit, 2000 grit, then finally 3000 grit, and a final wash before priming.
Since it is February, and I'm using rattle cans, I warmed up some water in a bowl, and placed my Tamiya Fine Surface primer in it to raise the pressure and warm up the paint.
Shot my first light coat of primer on, let it flash for 20 minutes, then laid down my final heavy 2nd coat. The end results are amazing, and smooth as glass. I did have 2 dust particles float onto it though during this. One on the hood, and the other on the passenger door.
I wet sanded these particles out using 1500 grit followed by 2000 grit. Then, I proceeded to do as I do on a 1:1. I wet sanded the entire primed body with 2000 grit sand paper. Upon doing so, I broke through the primer in some areas, going back down to the molded red color.
Here is my question, finally after all that nonsense you read, lol.
Should I have to re-prime the car since I broke through the primer back down to the molded color?
Thanks in advance and here are some pictures of the primer before and after sanding.
