Silicones have to be the worst, seems that you can wash whatever the part may be till the cows come home and there will still be a small amount left behind to screw up an otherwise perfect job.
++++++++++++++++++ I learnt all about this when some idiot picked up my "clean cloth" to shine up his motorcycle saddle - using a silicon based polish. I could not figure out why my paint job was going horribly wrong. As it turned out, I had used that cloth to wipe down just before spraying. 20/20 hindsight. After much agony, this is what I learnt: Keep any polish, wax, Lube, etc. that contains ANY silicon well away from anything (or any place) remotely connected to spray painting (including any rags that may be contaminated. Many of the aerosol magic lubes, penetrating oils etc. are suspect - check the contents (read the can) If you have contamination evidenced by small craters or "fisheyes" forming in the freshly applied paint (the paint is actually being rejected by the surface) - the normal reaction is to suspect water or oil from the compressor. DON'T sand (water paper) the area as I did, hoping to sand away the problem - this actually spreads the contamination and embeds the silicon into the surface making things even more difficult. There is a solvent that will remove the surface contamination. It is expensive and difficult to find, but it works if you wipe down two, maybe three times using a clean cloth literally with each wipe. (I use paper towels). Main problem was finding a paint or body shop that was aware of the stuff and would sell a small quantity (one pint or less). There is also a spray additive - a few drops in the gun will do the trick. Also not cheap and those who have (sell) it are secretive as to what it is - always got mine in a glass jar with no label. Some say it is the same stuff as the cleaner - I don't know, it may even be cold tea for all I care, but wiping down with it, plus a few drops of the additive in the gun will solve the problem. I have come to believe that you have everything over there (in the US) -probably manufacture the stuff - so if I can find it in Africa, you will no doubt have it there. Steve J
