Boy, will I be glad when this is over! It seems like I've been working on this cowl for months! !st thing today, I mixed up a small amount of smooth prime and painted it on the cowl in small sections, and then used a credit card to squeege the mixture into the pinholes and voids. I went over the entire lower cowl this way. I painted the front of the cowl with the remaining mixture as this is the place that tends to get sanded through due to all of the compound curves and edges. the credit card trck turned out to work VERY well, there were virtually no pinholes detected when I sprayed the 1st major Heavy coat. I let that set up for several minutes and then went back out and sprayed another heavy coat. I was hoping that by putting on two heavy coats that I would not have to recoat after sanding but.... I started out sanding w/ 220 grit, hoping that would eliminate the need for recoating, but I found some spots that were going to need recoating anyway, so I switched to 100 grit and sanded the entire lower cowl. The front around the Ram air intake and the cooling intake rings and spinner ring were difficult due to the narrow amount of room and my fat fingers. I'm debating respraying, and thing that I will use the paint brush again and only recoat those areas where it's needed. We'll lsee how it feel about it in the am.
