plastidip is easy to use, no need to sand, just clean it and give 4-5 coats. the thing i like about plastidip is if you dont like it you can just peel it off.
get a 12 volt relay, pin 30 goes to battery, pin 85 & 86 go to high beam ( doesnt matter which one goes to pos. or neg), pin 87 goes to low beam (positve if its positve trigger, negative if its neg trigger.)
Its 4.29 in my town and we fucking make the gas. The trucks literary have to drive 20 minutes from the refinery to my town. It should be hell of a cheaper. A 3 hour drive to a city that doenst make it and its 20 cents cheaper.
6010 would be the choice if your doing what he made the video for, off roading, something breaks. 7018 would not be good because all your base metals would be very dirty, and if you off road a lot they might be rusty in certain areas. I love welding with 6010 because it so more forgiving than any of the low hydrogen rods. i wonder how it would weld with more than 3 batteries?
ive done it many times with no problems, some vehicles you have to leave the stock charging wire on. my friends 98 durango charging wire ties into his starter wire so we just added 1/0 to it with 1/0 grounds. it may make your lights dim worse cus after doing the big 3 the wires are no longer restricted so it allows more power to flow through.
some vehicles have a separate ground on the alt. just find your charging post. if your alt has a few different posts just use a dmm to find the charging post.
There are places here where that is considered warm. A couple hours away from me where they have highs in the -38 degrees. Dashes haven't cracked....so weird. Not saying you're wrong, just saying I have vehicles that sit in -50 average in the winter time with 0 issues.
hell yea, up here it gets fucking cold. for all the years ive been up here ive never had any issues with anything cracking or breaking because of the cold.
