I'd have to go through my notes as a refresher, but first - practice on scraps!
I tinted the filler, so after it was mixed, I scooped it onto the body and hand rubbed it in. I believe after letting it sit for a short period of time, I took an old credit card to scrape it off. Possible after a bit more time, I used a dry rag to wipe the body down. I'm pretty sure I followed the instructions on the can at the time. I can look them up tomorrow.
