I used USC featherweight autobody filler (U.S. chemical & plastics) no.21330
Just ask for metal straightening in a can lol.
I use lots, even if a very small dent put on sand off until it is real close (my car is black) so it has to be straight.
Then followed by 2k high build primer, same thing spray on sand off (wet sanding)
To check for straightness is to wet with water then have a light at the opposite of
the way you are looking and eye ball it.
These are my opinion and I am not a body person by trade (self taught) and alot
of mistakes along the way.I am 49 and have been doing alot of cars since my mid 20s Study read the web and so on. Make sure the surface is clean (wax and grease remover).
Oh also were gloves as there are oils on your hands even if they are super clean.
Every one has a way they do things, hope this helps you.
