Thread about drop backs and "fillers" in compounds

Light wipedown vs Full wipedown - Detailing World

 

I would advise caution when using strong solvents

Solvent Cleaning

There are two main risks associated with using aromatic hydrocarbon solvents; both relating to the effects of solvent on the organic binder of the paint-

(a) Possible extraction (leaching) of low-molecular weight components of the paint binder by the action of the solvent

(b) The more acute element of risk in cleaning, however, is that of swelling of the paint through sorption (absorption or adsorption) of solvent. The polymerised urethanes dried oil network may not be truly soluble, but the polymer network may swell by sorption of solvent molecules. Depending on the degree of swelling, the paint will be more or less softened and its capacity to bind the pigment particles may be affected. In the swollen condition, there is a risk that pigment may be removed from the paint through the mechanical (friction) action of a foam pad.

Note - Aromatic hydrocarbons- are the most toxic compounds found in petroleum products and include such substances as Para-xylene (benzene, toluene, ethyl benzene, and xylene) which are all volatile organic compounds

 

togwt, you always put great info!

 

I hope to be an asset to anyone who is new to detailing and to the professionals and enthusiast detailer’s who seek to advance their knowledge of detailing

 

again TOGWT is spot on with great advice

I don't use any oil based abrasive polishes except for 85RD FP to finish up abrasively once we are certain that the finish is truly perfect
We currently use Gtechniq P1 which is water based and has hardly any lubrication and have tested for drop back with IPA, Prepsol and De Beer/Metalux silicone removers (very strong solvents)

IPA 75/25 is best for a wipedown IMO. good idea to do a wipedown straight after you finish a step then let the panel cool and do another one.

 

so togwt ... let me get this straight.

I use a product similar to prep-sol and i'm pretty sure it contains "something"ene.

Sometimes IPA doesn't work that great and it doesn't show the true condition of the paint. What's your recommended method?

 

I was reading that thread; it seems scary to me that those guys used the harsh solvents they did in that test, it cannot possibly be good for paint to use those powerful solvents. I would rather have some filling than use those products on my car or my customer cars.

I respect the quest for revealing an honest finish but logically there seems to a point of diminishing returns.

 

I like using 1z Acrysol, better than IPA to show the filling properties of a polish IMHO.

 

Mario, do you have any more pictures that are showing filling? I would love to see other compounds like #105 and Menzerna.

 

Hi Marcus !!
I don't have more pictures... This weekend I'm going to buff a black car, I'll try taking pics of that.
Cheers.
