Yup! Mothers is one of those tips you don't soon forget once you have tried it. I forget where I learned about it, but it's one of those things you tend to get from other gearheads.
As for the slot mags, they are one of those things that look good on only a select type of car. A friend and I have been talking about them for a while now as a period type of thing that is cheap to buy (usually), but makes the car if you have the right sense of taste. Getting on my soapbox here... I for one don't like the Hot Rodding establishment today as the emphasis seems to be more on spending money and perfection than having fun with cars. That's why it seems everyone needs blingtastic giant wheels, etc. Happily for those of us who aren't slaves to fashion, sometimes what is cheap and functional is just as good. It may not get magazine covers, but it is infinitely more fun for those of us who build our own cars instead of paying a shop to do it for us. [/soapbox]
