Hi

Ive been using daved zinc 172 but not started stonechipping all they way through.

At the weekend i did the boot floor in 2 thinish coats and left it for about 24 hrs and then gave it a go with some stonechip run through a compessor (not the aerosol stuff)

and it looked ace, went and had a brew and came back and it had shrunk and reacted with the paint and was almost acting like id sprayed nitromors on instead. I'm wondering if it hadnt flashed off enough what with the weather being cold and toss.

Any other ideas and suggestions please because ive got to strip the boot floor off again on my back (i hate this i cant put in on my mates roll over jig as the rear frame is off whilst i paint it) and it bugs the C**p out of me doing jobs twice!!!

i've had problems with stonechip reacting badly with zinc primer. think i left it for a few days then did lots of very thin coats of stonchip, and eventually i buried the bad area of reaction.

im gonna re do it at the weekend and might try red oxide instead

Ive used red oxide for many years now with no problems

I've had stonechip react with etch too, It's always ok if you apply just a dust coat, and let it dry for 30 mins. Always let the stonechip flash off between coats, or it takes ages to dry.

on a dust coat ive had it shrink in the past aswell

what stonechip do you use?

[panelbeaterpeter]

Me? I use Tetrosyl.

Use a underseal product called U-POL Raptor. Its a 2K underseal that is excellent! (dodge, Ford, etc use it to coat the flat bed of big pick-ups in US) It also allows you to mix it with base coat, so colour code the underseal. Looks Ace when done!

i'll have a look at that the stuff ive been using is tetrosyl its all you can buy round here as the factory is about 15miles away. im not a big fan of it

i'll look at that upol stuff
