Default How do you remove hardened tree sap from roof?

I parked under a tree on a hot day and now there is tree sap on the roof of my car. I tried to wash and wax it off, but it is hardened. I almost want to try and crack it off, but I am afraid to scratch up my paint. I even tried bug and tar remover, but it did not work either. Any suggestions?

Try claybar. Remember to use alot of the lube spray that's usually provided in off the shelf packs.

The Bug'n'Tar remover will work. DONT try to scratch it off with your nails. Keep applying the product - leave it on for a bit and keep rubbing it. It will eventually come off. Scratching might damage the paint if you get too close to the coat...

Tree Resin (Sap):
(Appears like a dark brown/ red coloured raised surface mark) some of the most common resinous tree sap types are: White Pine, Walnut (also secretes an oily residue) Maple, Oak, Popular, and Blue Spruce, none of which are water soluble, the acidic content of the sap will etch the paint surface; causing a concave surface.

A lot depends upon the type of sap, which is actually an acidic resin emitted from the tree, the resin deposits can be removed by allowing one of the following to dwell on the resin for approx five mins; Isopropyl alcohol (IPA), a safe solvent like Stonerís Tarminatorô, or turpentine (especially effective on pine resin) which is made from tree resin, in severe cases it can be used to break down the resins in tree sap, use as a last resort only and use sparingly and do not rub hard and give it some time to work (dwell) use detailerís clay to remove any surface debris once resin is removed.

Once you remove the sap deposits, the paint or clear may be cracked, which may entail some expensive refinishing. Factors as to the amount of time it takes to remove sap and what damage it has caused are dependent on temperature and time the sap has been on the paint surface. Be careful and take your time removing it, remember always let the products do the work for you.

Tree sap that is still soft can be removed by soaking with Isopropyl Alcohol (or Stonerís Terminator) wet the area with the product and allows it to remain on the surface for 3-5 minutes, then wipe with soft dry towel. For tree sap that has hardened, carefully scrape the top of the spot off with a plastic razor blade to expose the softer sap inside.
