Upol Gravi Guard - too thick or reaction with primer?

[Sensibleboy]

Had a little repair in the car wheel arch and the bodyshop sprayed primer over the new spot welds. I sanded this lightly and sprayed upol Gravi Guard over the area.

I'm not expert enough to work out if it's reacted with the primer or I've simply applied it too thick.

Can anybody tell from the picture?

That’s reacted. Gravi-guard/gravi-tex is very sensitive stuff and will pretty much react with any 1k product (aerosol primer) if applied too heavy. If you have to use it I suggest doing very light coats and let it nearly dry in between coats.

reaction from too much /too soon ....its very high in solvents so best built up slowly with medium coats

Thanks guys. I've sanded it down slightly and given it another thin coat. It sits behind the arch liner so doesn't need to look too pretty.
