I had a bottle of this, lasted me for years. Ran out recently so went to local autoshop that stocks Autoglym to find they had none. Bought the Carplan version that they had- not a patch on Autoglym tbh.Auto glym tar remover been told works well , removes carpet glue good
If you imaging the paint surface as an orange ....dirt and crap build up in pits ....the clay will pull out the dirt and clean the surface prior to polishing.....a surface degreasant would remove tar spotsWhat about clay bar?
Completely agree with this, and your previous post. Tar remover, then something to remove iron particles and fallout (Auto Finesse Iron Out is very good) and then if you still really need to you could go with the clay bar.However well lubed, clay will risk maring the paint. It's best used for the final light finish, rather than lifting off the big stuff. That should really be done using the correct chemicals so that the process is as touchless as possible.
