Hello all - First post. First time building a pinewood derby car since 1983! Does anybody have any suggestions/guidelines as to the pre-paint weight my son's car should be? (I have no real world experience knowing how much weight the primer and paint will add to the car) My son is racing in his pack's PWD in a few weeks.

I think that weight would be damn close! (depending on number of coats and how thick) It would better to be a touch light and add a bit of putty to bring it up. you can also use aluminum tape (air duct tape) or even layers of clear packing tape to bring it up to your final weight.

I painted a car with primer and 3 coats of the spray and it was less than an 1oz of change it .03oz. So get the car as close to 5oz then add the paint. Like IAE send if you use the aluminium tape you can just pull off and drop weight or just drill very small holes in the front of car to drop the weight.

Welcome to the forum. I don't paint anymore. When I did paint (I went by grams) I would usually put about 20 or so grams of primer, paint and clear on the car. I would let it dry, weigh it and bring it up to my total weight by painting. 20 grams of paint is quite a bit of paint. But, I used Duplicolor Primer Filler, it's thick and heavy.

We didn't paint last year either. I sat there thinking about how much work I did to remove as much wood as possible, and there we were adding it right back with paint. .03 oz is quite a bit of wood. We had 3 cars last year. One we covered with the aluminum tape which looked pretty cool. The second we just stained, and the 3rd we used monokote.
