k, well I tried IPA, it worked Ok at best. Would have to apply ALOT and rub with MF towel.
Goof Off basically did nothing.
Glass Cleaner (No Name..hehe) Did nothing.
Haven't tried clay, I used to have some old used clay around, couldn't find it. Not going to use my brand new Ricardo clay for this on my "beater" car.
Checked under the sink, saw some vinegar (5% acetic by volume) only a small amount left.
Poured about a dollar size amount on the paint, used a blue shop towel to spread it a bit, felt smooth.. Hmm, widened out the product abit more on the paint, and I literally cleaned 1/5th of my hood 100% clear of sap with the vinegar.
Rushing out to Walmart now to get a new bottle.
Will wash car clean, then use vinegar and old MF towel then wash again and apply LSP tomorrow.
I Googled some info and apparently it should be safe for paint.
Also it said it can be used to remove water spots in this article.
