Copying a previous post here, bc again this gets asked so often.
Your options are:
Solid neoprene rubber strips and/or sheet (Amazon / Ebay)
Rubber d-shape sealing tape
Closed cell neoprene/EPDM/PVC foam tape (aka weatherstripping tape) (Amazon)
Open cell neoprene/EPDM/PVC foam tape (aka insulation tape)
Pour your own urethane or silicone gasket

Butyl tape (Amazon) - not good for adding height, great for sealing. Sticks to everything, never hardens.
Neutral cure silicone sealant (Amazon) - not good for height either, good for sealing.
You can buy foam tape in both high density and low density versions. High density == firm, low squish, doesn’t soak up surface imperfections well. Low density == soft, very squishy, conforms to weird outlines.
Closed cell == waterproof, dustproof, etc.
Open cell == swiss cheese. You probably don’t want this for an enclosure.
Solid rubber is very firm, but works great as a riser. You’ll need contact cement to adhere it to your deck and a hollow punch bit to create holes (you can’t drill rubber with a normal drill bit) for your enclosure fasteners.
Closed cell high density neoprene foam tape is easy to apply yourself, easy to cut, and the most popular choice. You don’t need someone to create a custom gasket for you. It’s also much cheaper. Measure the height you need and the width of your enclosure flange before ordering, or order twice (ask me how I know).
Make sure your gasket goes on the inner side of your enclosure screws, otherwise you will get dirt/water through your screw holes into your electronics
