Re: 7.6 Convertible 'C8' - Paint Project #2 - AKA - "Dirt & Snow - Move Aside !"
Sorry to hear about you paint problems. I call what happened a total finish failure.
Whenever I have had problems with paint it has been due to one or more of the following reasons:
1 - water based paint/primer - never use a water based coating on ferrous metal.
2 - wrong primer-paint combination.
3 - surface contamination - oil, grease, etc.
4 - wrong thinner
5 - old paint
Whenever I had paint lift off the primer, the cause was:
- wrong paint and primer combination
- old paint
-wrong thinner used
The only solution is to strip it all down to the metal and do it again. There is no hope. If it hasn't stuck after a few days, it isn't going to ever stick.
If you bought SW paints, call the store and have the product numbers handy. They will also want to know what the ambient temperature is where the paint is curing. They will tell you what is wrong.
Xylene might be the wrong thing to use with your paint or primer. Does the Product Data sheet say to use Xylene to reduce or for clean-up?
I use either mineral spirits or Naptha to clean and prep the surface. Either is pretty mild and works well.
I stay away from the SW All Surface Enamel primer. I don't like it at all. It is good for projects in the home, but is lousy for machinery or outdoor equipment. It is just too soft.
If you are using Sher-Kem paint, there is a specific primer for that. The primer needed is listed on the Sher-Kem chip chart. If you are using a primer with the SW Industrial Enamel, then I would read what it says on the Product Data Sheet. I don't use any primer at all when I paint with Industrial Enamel. I don't paint Gravely stuff with Indutrial Enamel. I use it to paint machines like Bandsaws, Lathes, etc.
For outdoor equipment I am using SW Acrolon and prime that with the SW Recoatable Epoxy primer. Acrolon is a Urethane paint and is very hard (3H).
If you are using Sher-Kem, use the optional hardener. Not only does in make the paint harder, it also removes the recoat time restrictions.
If you are using a paint from Tractor supply and a SW primer, then I would say with a high degree of certainty that the paint-primer combination is the cause. The solution is obvious.
Sorry that your job turned sour. It happens every now and then when using a new product. On the plus side, stripping that fresh paint off should be easy. Spray or brush the remover on and then hit it with the power washer.
