Which LSP is the most resistant to getting water spots?

[wannafbody]

Just a thought to ponder for the carnauba fans. If waxes really could protect better than polymers wouldn't car manufacturers just skip the clearcoat and slap some good old carnauba on the paint? Remember those good old days when paint faded and oxidized in a few months:nixweiss

Supe, I don't want to steer this thread off-topic, but would you mind sharing some general thoughts on Menz FMJ?

It's just ok stuff. It looks good and gives decent protection, but the durability (for me, at least) was just a week. My whole container of FMJ rotted after spending a summer in my garage. Not just separated, *rotted*. Smelled rotten and had big rotten chunks in it.

Why not just slap a layer of sealant on it, then? Comparing a sealant to a wax is a fair comparison, but comparing *either* a wax or a sealant to clear coat is not. That's like comparing a crayon to paint.



Clear coats are usually two part aliphatic urethanes with more in common with epoxy than sealants or waxes. They are not water based (like sealants are), and are not wax based.

Um...WHY DON'T YOU JUST USE THAT ALL THE TIME?!?!?!?

The good parking spot is reserved for my Cobra. I left it at work specifically so I could work on the Van hood over the weekend. Had to have my wife drive me home from work, and then back to work just to deal with this.

Ok man, I was just messin' with ya!

I know. I knew someone was going to say that anyway, haha. Just seeing who would be the first.



Have you guys ever seen water so hard that just filling up a glass from the faucet it would all be white for a while before it cleared up? That if you left a glass of water on the table, that as it slowly evaporated it would leave a trail of white crust down from where the water line started to where it currently was? This is how it was in my old apartment, and was even more odd since supposedly the complex supposedly had a water softener and I'd see the guy change out the bottles of chemicals every so often.

Think some watersoftners use a salt of some form to soften the water (not sure exactly how it works) The crusty stuff may have been the chemicals that they used.

IMHO, there is no way you can avoid water spots from sprinklers. You can QD it is the best way after it gets sprinkled on.

Aren't modern paints water based? Isn't paint made from polymers?

Nope. They are still two part systems related to epoxy resins. Lower VOC than they used to be, but you still wouldn't want to spray without a respirator.



Edit: Some single step clear coats have polymers in them, but polymers is not synonymous with water. Some two-stage aliphatic urethanes also have polymers in them, but again, they are not water based.



Here's a link to both an aliphatic urethane two-part clear coat, and an acrylic laquer: Car Clearcoat
