dailysleaze Posted February 26, 2012 Share Posted February 26, 2012 Forgive the amateurish attempt, but i'm trying different methods/paints to see what works to patch up rusty bits and to learn from my mistakes. I've come across the filler primer rippling like a skin on rice pudding. Does anyone know what speciifcally causes this? It's 3 coats of Halfords filler primer over no1 rust beater and some filler. I sanded slightly and degreased before spraying To be honest I wanted to see what happened and see how it goes with what I had at hand. I can always go back to metal and start again.

Briarston Posted February 26, 2012 Share Posted February 26, 2012 Looks as though you could have put on too much paint too quickly. Can't see too well, but looks as though the top coat has dried out over the previous coat(s) before it/they had gone off. Try putting on the first coat "light and dry" and let it go off before reapplying. Quote Link to comment Share on other sites More sharing options...
Jimmy Two-Jacks Posted February 26, 2012 Share Posted February 26, 2012 Too much too soon has caused curtaining by the look of it. Follow the advice regarding re-coat times on the tin. It can also be caused if your top coat is incompatible with the primer coat or old paint. Quote Link to comment Share on other sites More sharing options...
dantd5 Posted February 27, 2012 Share Posted February 27, 2012 Lots to learn here. I have this problem on some hinges I painted recently.... (Not capturing thread though) Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted February 27, 2012 Share Posted February 27, 2012 I tend to take the view that filler has no place on a Land Rover, they wear dents and scrapes with style, and filler leads to cracking if the panel flexes etc, water in the cracks helping corrosion underneath the surface... brush it back to clean, kill the rust and then hit it with some industrial-strength zinc-rich primer or similar. If you want a shiny finish after that, sand it down & give it a top-coat. Quote Link to comment Share on other sites More sharing options...
dailysleaze Posted February 28, 2012 Author Share Posted February 28, 2012 Cheers It seems to have dried alright and would sand down nicer. I guess the fact that it was 10 degrees C didn't help, but sometimes i'm a bit too impatient with painting... Quote Link to comment Share on other sites More sharing options...
big len Posted February 28, 2012 Share Posted February 28, 2012 This also looks like it could be reaction between the different paint bases ... not all paints were born equal (cellulous, acryllic, 2pack, water etc) and if you put one over another you can get reactions like this - easy way to avoid it without going into detail is to try sticking to a single brand for primer base coat etc Quote Link to comment Share on other sites More sharing options...
wack61 Posted February 28, 2012 Share Posted February 28, 2012 it looks like you're getting a reaction , did you use acid etch primer or normal primer, if it's alloy you're spraying you need etch if there's any bare metal You'll never get good results spraying in this weather , wait a couple of months until it warms up a bit Quote Link to comment Share on other sites More sharing options...
DrRob Posted February 29, 2012 Share Posted February 29, 2012 some industrial-strength zinc-rich primer . Any recommendations ? Quote Link to comment Share on other sites More sharing options...

There was no bare metal and the primer is Halfords filler primer. You'll never get good results spraying in this weather , wait a couple of months until it warms up a bit I think that can be said of most LR jobs!
