First time use. Very happy with experience.
I used this as primer for an old mower hood I was restoring. It did a great job filling in the low spots and helped provide a smooth finish. I was very happy with the finished product after using this primer.

great spray pattern, works well with plastic, and hides blemishes.
used this to paint some chrome trim around the front grille of a 06 Acura TSX. It had lots of rock chips and dings so i wanted a high build primer to fill it in. i didn't do much sanding before since it was going to get chipped up again after a month of driving but the SEM primer filled in nearly everything smooth. the best part is they use a great spray nozzle. did 3 coats and every time i used it it was a nice predictable even spray pattern with no splatter. came out perfect, easy to sand, and easy to add a few extra coats in spots that need more build up. i had no intention to make the trim piece perfect before paint but it ended up perfect thanks to this primer.

Best primer I've ever used (and I've tried a lot), but you pay for the best
I couldn't believe I had been using inferior primers in the past until I tried SEM. This primer sprays on smooth and the high build formula fills in tiny pores and pinholes with 1-2 sprays. I used the High Build Primer on some custom speaker pods I'm fabricating, and the drying time is fairly quick. I also liked how the primer stayed together even after sanding with 60-grit, other primers would start to chip off but not the SEM primer. I wanted to give this 5 stars but even though the end results are better than store-bought primer, you still have to pay about 4-times as much for the SEM stuff. If the price was a tad lower it would have gotten the full 5 stars from me.

SEM is great as usual
This is a great all around primer. It works exceptional on bare metal, plastic, and even wood. Even one coat of this primer has enough build properties to cover most imperfections and then a light dry or wet sanding on it gets it looking perfect. I just recently used this primer on a sub woofer enclosure that I made from MDF and it really helps to get it smooth for painting. SEM primer is great, as usual, as are all of SEM products I've ever used.
