Prepsol - removing tar

[KrisMas]

I've just got myself Dupont Prepsol the other day and after reading some posts saying that Prepsol can also be used to remove tar, I gave it a test today. Didn't find any directions on how to go about so tried the following method:

Clean down using Last Touch
Spray and let dwell for 30 secs
Wipe off with a piece of old mf

(Please disregard everything else other than the tar since my intention is just to test prepsol vs tar and those whitish spots are embeddedfine sand/dirt that I would clay afterwards during a proper detail)

Before - dried up tar



During - dissolving tar



After wiping with and old mf - disappearing tar



After 2nd application (same method) - disappeared tar



I was overwhelmed by how much tar prepsol had dissolved and removed after the first application but unfortunately there's still some remnants of tar residue that I wasn't been able to wipe off in time before they dried up again (note the brownish stain in the last picture).

Please comment/suggest a proper/more appropriate method to improve.

Thanks in advance.

I did something similar with 3M Adhesive remover on my moms car a few years back. She ran through something that tossed up a bunch of tar on her passenger front door. It probably took me 30 minutes to remove it all but I was really happy with the results.

I just used a cheapo yellow flannel cloth for mine.

You should just be able to use a little prepsol on your cleaning rag to get that stain up?

I don't know why it didn't even occurred to me to try that.

I'm guessing this is sarcasm?

No...really...honestly....no sarcasm intended...it didn't occurred to me at all....I was thinking more in the line of doing another spray and wipe. I was cranking my head and didn't even think of a simple wipe could have done the trick.

Purple Power works really really well also.

Tarminator + Bug/Tar Sponge is my go-to for this sort of stuff. It works absolute wonders.

You can see how it removed a bunch of crap from the Mercedes in my thread here...

I tried WD-40 for the 1st time on my wife's white Vette and was pleased how easy it came off. Would Prepsol damage the paint if used too frequently?

This is what I found in the tecnical manual for presol:

Substrates
Unsanded substrates
OEM finishes
Cured, repainted surfaces
Note: Do not use on unprimed plastic or fiberglass substrates due to possible static buildup, which may cause a flash fire

So I'd suppose it's safe on paintwork, if used properly.
