discussion pre painting wipes

[Guest]

i have been watching a lot of car shows lately mainly wheeler dealers on discovery channel in the uk and i have noticed that when the mechanic is doing some kind of body repair one it has been sanded and primed he uses something called panel wipe which get rid of all the impurities that can contaminate paint and spoil the finish.


i've often wondered if we could use this stuff on our models after priming or sanding them or if anybody knows of some kind of alternative that we could use ?

I use a "tack rag" ......... I first used them when I did my apprenticeship 35 years ago. They are good for getting rid of any dirt and dust present and they leave no chemical trace. You can get them from any good decorators merchant.

what about getting rid of greasy marks and fingerprints

I brought some prep wipes (pkt of 5) from halfords..... And just tear a little bit off one at a time..... Seem ok to me, i use panel wipe at work, but the fumes are probably a bit to heavy for home use.

I usually wipe the model with isopropyl alcohol to remove any greasy paw marks. After that I only handle it with 'latex' gloves on, which protects the model and my hands (from paint).

Iso (Panel Wipe) then tack-rags, just the same as working on the real thing!

Found these which are wipes ie not tack rags.


ArtoolStudio Wipes 12 to a packet.


Also from B & Q Dial Decorators wipes 24 packet.


Both contain Isopropyl.


Tack rags I find are good for getting rid of those small hairs just before airbrushing. I only lightly touch the surface just enough to pick up any hairs. They will not remove grease or finger marks etc.

good idea steve i was thinking about using them but i have run out of them as for the isopropyl alcohol what type of cloth do you use it with ?

I wipe the model down with isopropyl alcohol using an old,clean cotton 'T' shirt.

One thing if you are using acrylics using neat Isopropyl will act as paint remover.


Even acrylics well cured will be softened. That is water based no idea with non waterbased acrylics.


I would recommend the wipes on acrylic as the amount of isopropyl is weak.

I wipe the plastic, before any paint is applied, isn't that the whole point? After painting has started I try not to handle the model without gloves and to keep handling to a minimum.


My IPA (not the beer) is nominally 90%, but you can always dilute it with water to make a less aggressive solution if you need to wipe paint already applied.

I doubt that most use gloves as you do Steve. I certainly do not I have enough problems with my old hands with a bare skin feel.


Definitely use before any paint is applied. But if, as I do not wear gloves, by the time I have finished there will be finger prep marks for each paint coat . Also as I wet and dry the wipes get rid of the dust accumulated particularly in the joints and nooks and crannies.

I wash the parts in waem soapy water and allow to air dry before painting.

I'm an Ipa and latex glove man as well. Well when using enamel or lacquers other wise it's just ipa. I wash my hands well and have been known to you the wet wipes to clean my fingers while working.


I use a clean soft brush and give the surface a good wash down with the IPA blow any solids away with an empty airbrush... Sort of works. Two cats can out do the best of vacuum cleaners, so the odd hair does get it the paint from time to time.

Meths on a cotton bud before I primer for me, when I can be bothered.

I use a product called PollyS Prep which I suspect contains IPA, and brushes on.
