Thanks for the response. A towel on the car seat is mandatory part of this routine. Mineral oil on car fabric is a serious problem. A towel works perfectly. Caution is needed when applying it. Cleaning up spilled mineral oil is no fun. Once home, I paper towel it off (the easy part) and hop in a bath. Even in the heat, the coating stayed on my legs where I applied it.
Last year was my first time using mineral oil. I'm trying to remember what I did with sunscreen. I usually use the spf 30 clear liquid pump since its so easy to put on. Sunscreens don't mix well with mineral oil. I seem to remember them separating on my legs and so instead I just kept my lower legs out of the direct sun. This year I may try to apply the clear 30 first and let it dry. Maybe the mineral oil will work over that. Chiggers are already starting to come out in Texas so this will be soon.
Ok. I was chicken to say this before but here's the rest of the story. There is one other exposure, so to speak. Since I only used mineral oil on the lower legs, chiggers are easily able to land on your upper legs and, well travel north. Being this is Texas, the solution really kills 2 birds with 1 stone. If you're willing to forego the (embarrassed smiley) undies and add a little mineral oil to where chiggers might be headed, you avoid getting bitten, well where chiggers have been known to bite people. Also, it is a
cool (ahhh...) secret that you don't have to share with your baking hot friends.
Sorry
I'm not too proud and I love the Texas outdoors too much to miss it just for chiggers. The freedom to stay out all day is entirely worth the effort.
