For sheetmetal, you want a very fine toothed blade.
32 teeth per inch is a standard that works very well.
Acrylic needs 18 to 24 tpi, depending on thickness, 18 ish for 1/4" (~5mm) and finer, 24 for 1/8" (3mm).
Always get the best quality blades you can get, the few extra dollars spent will be worth it in better and more consistant results.
Once you use a blade for acrylic, do not use it for anything else, keep it dedicated to cutting acrylic.
For cutting on a side panel, get a roll of 2" masking or painters tape, and put down 2 layers covering your side panel to layout your design on and prevent scratching the paint with the jigsaw as you move it along.
Be aware also, that all acrylic is not created equal.
There is some material that looks just like acrylic, but is much softer and usually less rigid, and melts at a MUCH lower temperature.
The stuff you buy to replace glass in a storm door usually behaves like this, but maybe that's a tradeoff for more impact resillience.
This stuff is garbage for trying to fabricate with. When you cut it, even with the right tooling, the chips just fuse together into a glob instead of falling away free.
I've watched it fuse back together just behind the jigsaw blade, and you have to go back repeatedly to try to re-open the cut line.
Usually, it has plastic covering the surface rather than paper, like everyone is used to seeing on plexiglas for example. Though not all plastic covered acrylic sheet is bad, I always try to get paper covered, as I've had a problem with it..
If you buy from a home improvement store, like a Lowes or HD, buy the smallest piece you can, and do a test cutting first if it's not paper covered.
I've also see the crap stuff more often in the thinner 1/8" variety, but I have on occasion run across it in 1/4" thickness.
Hope that helped a bit,
