My RX-7 has a lot of dried-up tree sap on the hood and roof, as you can see here:
I'm tired of people telling me to clean the bird E36 M3 off of my car, and I have some free time while I wait for the next batch of repair parts to come in. I was looking at the DIY clay bar topic and was wondering, will that get the sap off?
Haven't tried the DIY type clay bar. But I have found that the commercial clay bars are the easiest way to remove tree sap.
I use the clay bar from Griots Garage and have their special Pad/holder Clay and pad to use on my buffer.
Never tried this on paint before but peanut butter takes it off skin quite well. It might be worth a try.
The clay is bitchin, it took some nasty overspray off of my car.
Saps and resins mights be soluble in rubbing alcohol so maybe give that a try. They do make some stuff to remove it. I think the clay is a good idea though, like Hal said.
I've had good luck using a sharp razor blade.
Carefully (!) scrape parallel with the paint surface (but above the paint surface). If the sap is dried enough, it'll 'pop' off in a big chunk. The remaining bits can be removed with kerosene/yourfavoritesolvent.
I use Goo Gone, it takes some elbow grease but seems to do the best job of removing sap with minimal impact on the paint.
My dad swears to god that Vaseline will take it right off. I've never tried it, but he is pretty knowledgable on these things.
