Gravitex stonechip?

[Vixerfixer123]

Hi folks,will it be ok to spray gravitex over Jotun epoxy primer?

Yes, just make sure you follow the Jotun overcoat times or if you exceed the overcoat window sand to provide a key.

As i learnt the hard way,went to early,next day the gravitex crazed all over,you plonker rodney

You are better off using a rubberised stone chip like Dinitrol 447. It works better as a stone chip as it's less likely to chip than gravitex which sets hard.

This is Dinitrol 477 over jotun 87.

I fully concur with @RaceDiagnostics on this.
I prefer Dinatrol as well, the gravitex is just too hard when cured.

Thanks folks,think I’ll go with the dinitrol then

Next ? Folks is how many bottles to do an insignia underside?

I put 7 litres on the underside of my Alfa 75.

I used Sikaguard 6440 but it's similar to the 447

First coat of Sikaguard 6440 stone chip.
Used a cheap schutz gun and it didn't go well.
The same gun sprayed 3m stone chip fine and this worked ok for a while then the stone chip started building up around the tip and going on in lumps.
I had already preheated the stone chip which helped but all in all not great.

Was going to try another gun, or wait until the weather warmed up, but since I've a pressure pot I'd decided to give it a go. The stone chip isn't any thicker than the 87a after all.

Pressure pot is far nicer to use and gave a better (more closed)...

I need to finish this one first.
I tend to do the hard work and then loose interest.

I really need to get back and at it.
