wax and grease remover before paint

E

Edwin T Reid

Generously apply wax and grease remover to the substrate either with a cloth soaked with wax and grease remover or by spray applicator. Wipe the surface with a clean, dry cloth before the wax and grease remover has flashed off the substrate. If applying over primer or body filler, allow additional dry time before painting to avoid trapping solvents.

Any Thoughts?
 
I’ve read that distilled water, isopropyl alcohol (for a 20% dilution) and a little bit of dawn dish soap works well as a wax remover/degreaser.
 
No doubt it would dissolve wax and grease but I would really be afraid of residue from the dawn.

A quality W&G remover is designed not only to dissolve the the contaminates, but to float them to the surface. Furthermore, it is engineered to dry slowly enough to allow you time to wipe them off before drying.

A gallon of quality W&G remover is very inexpensive. I would never consider a home brew alternative myself.

To add to the above replies. Think of the cost of primer, paint and clear, then think of how important the proper prep work is to keeping that paint job from failing in a year or so.
Proper scratch on the metal surface, thorough cleaning with quality W&G remover and two coats of epoxy primer are essentials not options, IMHO.
 
I thought Dawn was best for floating stuff to the surface, thats why they wash the ducks and seals with it after an oil spill.

The resurrected Por 15 thread complains that it traps moisture and makes rust dissolve the cars faster, so why would anyone want to use anything mostly water as the last wipe down before paint?

Not really. They use it on the birds/animals as solvents will not harm or kill the bird’s.
Yes it works, but if it’s not cleaned properly, it can leave potential residue that could be trapped under the subsequent coatings.

I would not even try that, the soap could leave behind a thin film resisting proper adhesion, therefore making your paint job a urethane wrap.
