Painted the wife's kayak....Not good

You could try washing it with TSP. I use that stuff to wash whatever I'm going to paint. Mix up a good strong batch but it will also strip your hands of oils and fats too so use gloves or a brush.

Maybe another way to look at it-since likely you will use the canoe for travelling on the water body ,would just a plain camouflage net take care of concealing the red color while on shore hunting? Sure it would take care of the paint job.

get your self some steel wool scruff the canoe really good, wash it down let it dry and take the tsp solution give it a good wipe down. Once its dried apply the Krylon. if you want to try and smooth out the scruff marks try 2 light coats of primer.

How about some pics?

If this fails and you have no choice but to do something, I'd be contacting the manufacturer for suggestions and talking to local body shops as they paint plastic all the time.

X2 on the krylon, give it a thorough sanding first as well.

Sanding is the key

Looked great till the next morning. Power washed tonight and the paint came off in sheets.

I then washed it again with dish soap using a sanding block to scrub it. Then I rinsed it down with water.
After it drys and I will try to paint it again. The surface feels different now, less slick.

After a sanding, would washing it down in acetone help any to really get it clean before painting?

To permanently colour PVC (virtually all recreational kayaks are made from this) use petroleum dye in a methyl-ethyl-ketone base. No sanding required but a surface clean is advisable. MEK base will dissolve a layer a few 1/1000s of an inch deep on the plastic and open microscopic spaces between the plastic molecules. After application the MEK evaporates off completely and the dye is left permanently adhered to these spaces.

You would probably have to order the dye online but the MEK base is readily available as clear PVC pipe primer at most plumbing wholesalers. I use a brand made by Oatey and it is mostly MEK with a few other solvents thrown in.

Did a quick read of the Krylon Fusion paint MSDS sheets and it is similar except it is in an acetone base (similar properties to MEK) with a few other solvents thrown in for good measure. It likely works in the same manner.

I have the Acetone and plan to wipe it down, let it dry and use the Krylon I bought..Cross your fingers...I need the darn thing for tomorrow morning...
