Spray glue before painting

[71chevelle]

OK, so I painted my engine cover and it did not turn out right. The paint peeled off and then I had to strip the whole thing. I am trying not to take a brillo to it to scuff it up before I paint. I was wondering if I gave it a coat of spray adhesive before painting, would that help it stick better, or am I barking up the wrong tree on this one? Also, if it is a good plan, should I let the glue fully dry first, or should I paint while it is still takcy?

Try laying down a coat of primer first.

will the primer stick on that smooth surface

Re: Spray glue before painting

It's suppose to, it helps to stick to the material and allow the paint to do the same. I assume you cleaned it thoroughly? It will need to be cleaned so there isn't any grease or dirt on there.

cleaned it down with rub alcohol. I will lay down some primer, just was trying to avoid that.The color needs to be on a darker surface to look like the right color, and all my primer is grey. Oh well, just have to see how it looks

It'll cover up pretty good, worse case you will just need to lay down another coat. But you should be much happier with the result. Painting plastic is always tricky.

I think they make spraypaint specifically for plastic. I remember seeing it at Walmart.

I used the the duplicolor trim paint (spray) with no primer. I did it black again, from that plasticky black to nice deep clean new looking black. That was like 8 or 9 months ago and it didn't peel. Still looks good.

Re: Spray glue before painting

have to go at it one more time. Maybee I laid it on to thick the first time. And yes the fusion is great, unless you are looking for special colors. They are mainly red black green and so on. Well just gave it a good cleanin with some soap and water, and used a green scrubby to kinda scratch it some. If it turns out, I will post it in the painted engine post before a mod yells at me for the location of this

Re: Spray glue before painting

If you used the auto-spray for oem matching, that paint doesn't have much if any additional adhesion properties since it's designed to be used with primer. On some paints like trim paint, ceramic paint it's less crucial since it has different base properties but that said I would still use a primer imo. It's possible you didn't let it dry enough, put on too thick like you mentioned... a lot of variables from person to person and their method.

But good luck with it and let us know how it turns out.
