The Trunk Project/Dremel Opinions

Ok well Sunday was beautiful out, so I decided to take the 1 break in this crap weather and FG some car stuff. Pulled all my carpetting out of the trunk and the spare tire well. Started to FG it, well, turns out, I couldn't finish the first layer. Ran out of resin, and I was about exhausted. For doing something this size is it functional to just get the mat/cloth wet with resin(dip) and apply then smooth out or is the patting method with the brush best? The brush took a long time(I also had to deal with annoying ass wind making my foil fly up before I could FG the crap down, I finally won that battle). All I know is, it was really hard on my body to do that. (I was loosing basic motor skills towards the end with dipping the brush and applying because my body was so exhausted holding my ass like that for that long.) Anyways, now the weather sucks(snow, rain, cold, f that crap, I hate this state.) so I can't even finish the first layer or two to pop it out and bring it inside. *sigh* Any suggestions?

Also I am highly considering a dremel tool kit for working with this. It has a nice ability to cut and work well along the hand. Its only like 60-80 bucks locally with a good amount of accessories. I'm also planning on using it(for now) to possibly do everything I can with drilling/cutting/sanding. Given I know it will be weaker than a good wire drill and such, but they said it should be able to handle the MDF, just gotta be slow with it. Once I get the money I plan on getting a plunge router and a good wire drill. Prolly a good table saw too so I can cut the stuff myself easily enough. Just wanting to know opinions on the Dremel for now. Seems like it'd be a really useful tool.

 I love my dremel. it works great for tight spaces, cutting and sanding. for making rings it sucks, I break too many bits and it takes too long. great detail tool though.

Yeah, I don't think I'll ever use it for the rings. That's one thing I never intended on using it for. So you think it's well worth the money for a good starting tool?
