Recently I was able to view Mercury, Venus and Jupiter during daylight but was not able to find Mars and Saturn.  I used a 4 "refractor at 40x with an AVX mount. Has anyone had luck finding these two planets and if so can you share any tips?

Yes, I saw both of them with my previous 4" apo, but needed a helping object: a brighter planet or Moon. I saw Mars minutes before Moon occulted in 2008 at daylight, and Saturn near Venus later.

 

Use a planetarium software to find a close conjunction with Moon or Venus.

And internal baffling is critical to block the reflection of sunlight. Even sunlight reflecting from the edge of the lens cell is very disturbing.

Jupiter had very little contrast with the sky and was invisible when the focus was off even a tiny bit.

I've been able to see planets and stars as faint as magnitude 3ish with my 6" f/8 achromat. The trick for me is to have a spot accurately marked where my tripod goes so when I set it out in daylight the polar alignment is fairly good. I synch my mount on the sun and from there my GoTos are fairly good.

I aligned on the sun using a solar filter and then found and synced to Venus. After that Mercury and Jupiter were fairly easy.
