no inline water filter cause this?

camcruiser13 · 03-29-07, 02:01 PM

if i spray using a compressoer/air gun combo, will the water in the tank cause "fish eyeing"? for the longest time i have been thinking it was poor prep, but now im thinking its water?

anyone know

Condensation is not you're friend. It was screwing with my primer job till I got a water seperator/filter.

At least put one of those little $2 disposable filters at the gun. Your line probably has condensation etc in it.

Thanks Guys! I had that exact problem when I painted my bumpers. I'm going to paint them again and now I'll add a water filter before I do.

A lot of fish eye is improper prep, specifically not getting the surface clean enough.

Your fingerprints can cause it.

wax and grease remover, then do it again.

go to napa and get a tac rag/and solution also

Prior to painting...clean with Prep Solv (PPG) or Pre Kleeno (RM) or similar, tack it off, run an in line filter and go. Make sure you don't have one of those inline air tool oilers (more than just a fish eye with one of those puppies). Fish eye additive may help if it persists (available at your auto paint supplier). More often, I've seen fisheyes from waxes, grease, oils, (generally the bad prep mentioned above) and occaisionally air born dust/schmootz coming from a heater kicking on during the painting...I hated that one.

A little write up from the BASF site....

On a freshly painted finish, craters (a.k.a. fisheyes, pinholes) appear when a contaminant that
creates high surface tension prevents the paint film from flowing over it. As a result, the paint
forms a ring around the contaminant, creating what looks like a circular indentation with
raised edges.
Sources of contamination that cause craters include: oils, fats, waxes, polishing and sealing
compounds, airborne oils and waters, and many types of personal care items such as
hairspray, deodorant and lotion. Only a very thorough chemical cleaning of the areas to be
coated can prevent craters from forming.
If craters have formed, sand away the contaminated topcoat layer, clean thoroughly, and
apply a fresh layer of material. Alternately, a fisheye eliminator may be used to lower the
surface tension and allow the paint film to flow over the contaminants. R-M makes two
products designed to reduce the effects of silicone contamination.
809 Fisheye Eliminator
�� Eliminates fisheyes without causing orange peel.
�� Use in R-M Clearcoats only.
�� Do not use in Diamont Basecoat or R-M Undercoats.
�� Add 2 oz. per gallon of RFU clearcoat.
812 Stop Silicone
�� Use in UNO-HD only.
�� Do not use in Diamont Basecoat or R-M Undercoats.
�� Add ¼ to ½ cap to one quart of RFU UNO-HD.
�� Apply 1-2 very fine coats in the areas where fisheyes have formed.
�� Allow solvents to evaporate between coats.
Please be advised that these products should be used as a last resort, and only when a
thorough cleaning of the substrate and spray equipment has not rectified the problem. If
used, all equipment should be cleaned thoroughly with clean (virgin) solvent-based cleaner in
order to reduce subsequent contamination.

Been there, done that, only to be told after the fact that you shouldn't use fisheye elminiator in catalyzed paint.
