Full sun decorative redwood siding

Hi, I am looking for some redwood siding product advice.

We have a contemporary house with sections of horizontal running redwood architectural accent siding on the exterior walls. The sections on the south facing walls get full sun, and have been refinished twice in 3 years due to cracking and peeling of the clear coat, under warranty repair by painter, but a year later and now it is my problem.

I am located near Los Angeles, so product must be locally available, i.e. low VOC and water based, and easy to use for an amateur like myself.

I do not know what product the painter used, "good stuff you can no longer buy", and the color was custom mixed to the clear base.

For my own repairs, I have had very good results using Wood Kote Jel'd Stain, and Modern Masters MasterClear Supreme on mahogany patio doors, also in full sun. These doors were painted with the same product that is failing on the siding. I sanded the doors to bare wood, stained, and applied semi gloss clear coat.

I do have a redwood fence painted with Sikkens Cetol SRD Translucent Wood Finish Dark Oak, the color was a compromise between me and my neighbor. The Cetol SRD looks good on the fence, but it is too dull for the siding.

My plan was to sand the siding to bare wood, stain, and then semi-gloss clear topcoat with the MasterClear Supreme.

I've sanded a couple boards of the redwood (don't know why it is called redwood when there is almost no red wood?) siding to bare wood, and applied several Wood Kote Jel'd stain color samples, but the color is not right.

I can mix stains to get the desired contemporary house redwood siding look, or I can find a different product with the right color out of the can.

I saw the Benjamin Moore Arborcoat Translucent Waterborne Stain Redwood color in the store, color looks good, but I don't know if it will hold up to the sun, and I have seen many negative product reviews where the product is use on decks, not so many negative reviews when used on siding, but still.

I don't mind the effort to sand to bare wood once, and apply products I can readily buy again, but I would want ongoing maintenance to be maintenance only.

Any techniques and product recommendations would be welcome.
Thank you
