Too late to help now but maybe someone else will benefit. I gel stained my Pella fiberglass entry door 6.5 years ago and it looked great! Used Minwax gel stain and their spar varnish, as directed by Pella. However, it did not stand up to weather at all. It chipped and had to be varnished again every 6 months. This Spring it chipped all the way through to the fiberglass and pulled stain with it! Believe me, I did everything properly. My door faces south east and has no roof. But a neighbor whose fiberglass door faces north had the same trouble - he used the same products as I. My neighbor got disgusted and stripped his down to fiberglass and restained it with Sikkens products 3 years ago. No trouble since. Sikkens makes a Door and Window stain that does not require varnish over top. Fortunately for me, just before I started stripping about 36 layers of varnish off my door, it delaminated! Pella brought me a new unfinished slab (under warranty) and I'm using Sikkens to stain it. I've been told the varnish is the trouble. It's like putting a sheet of glass against the door, trapping the heat. Plus it isn't flexible enough to expand and contract. If I put up a storm door to protect it, the problem would've been worse due to trapped heat. Sikkens is specifically made for fiberglass doors. I don't have any vested interests in the company but thought I'd try to help the next guy... Here is a link that might be useful: Sikkens Door and Window stain

It's easy to get a perfect finish on painted furniture when you spray it, but it's true it is hard to get it perfect without spraying. I would stain them if they were mine, just because maple looks great stained and stained furniture is easier to take care of, but this probably depends on what else is around in the room as well. If you stain, you want to stain, let dry, apply one coat sanding sealer and then at least one coat of poly. There are water based finishes on the market now but I don't like any of them. Lacquer can only be sprayed so. You want to lightly sand after the sealer coat because applying any first coat of finish on stained wood will raise the grain and make the surface very rough. The easiest way to apply stain is with a staining pad. Using gel stain or not won't make a difference to your wrist.

Ok- here is what I have, and what I've done.. 1- On a bathroom vanity that was standard oak. I used GF Georgia Cherry 4 coats 24+ hours dry time between each coat. Appling with sponge/foam brush- waiting just a few minutes then wiping.. then 3 ( 4-6 hour between coats)of GF high performance top coat.. I love love love them!!! (pic included) 2) mast bath vanity. the Mr. decided he wanted the java on first and then go back to our Georgia Cherry. No problems at all with the java coat - or the first coat of GA cherry on 1/2 the vanity.. Then the spots started showing up - and areas that looked like I wiped off too much.. After reading all the above comments. I now think it is because I didn't let the areas dry that I touched up... will sand a little and retouch

Take it from me, if you can afford new cabinets - do it! A fresh coat of paint or darker stain will definitely help, but you'll probably still be left feeling like your kitchen is somewhat dated. You have a great space to work with! I had the dreaded orange oak cabinets too, so I feel your pain. I couldn't afford new cabinets about 5 years ago so I painted mine. I didn't want dark/stained so I picked a soft gray color. By the time I put in new granite, BS, appliances, ect - well I should have just saved up and bought new cabinets. Oh well, lesson learned... But I DO love my kitchen after all the work. I love it wayyyyy better than my old space so I don't regret the decision to paint, it's just that my kitchen still feels dated so it's only a matter of time until the soffit comes down and I get new uppers... To sum it up, paint or stain will definitely improve the space. But new cabinets will make a bigger impact so if you can afford replacing everything then go for it. If you do paint, use quality paint. It's not cheap. I used BM Advanced paint. I won't use anything else going forward. I have found dried food on my cabinets and picked it off with my fingernail and the paint never chips or comes off. Here are two examples in my home. The first is my kitchen. I painted instead of replacing the cabinets. I love the space but it's not my dream space. before after Now here's my second example. This time we replaced the ugly oak cabinet. See what I mean by new cabinets making a bigger impact?
