General Tidying up peeled bodywork

[norspeed]

Hi, i have today used this laquer,
https://www.ebay.co.uk/itm/176366750754

To repair the peeling laquer on my red 2010 fiat 500.

When i spray it on my car it dries to a white rough finish.

If i wipe it off before it dries it comes off like sticky snow.

I have tried using it outside in a temperarure of 15c, and also inside out of the breeze at the same temperature.

I have also tried warming the can up in a bucket of warm water to see if that helped, but it is still no different.

I have had this problem before with this laquer, is there issue is with this product ?

Can anyone advise ?

IMO, you cannot spray over peeling laquer to repair it. It must be completely removed, and a new coat applied.

Spraying outside is asking for trouble, as flies, bugs and dust will always find your freshly applied coat of laquer.

If it looks like a white dust you have not applied it thick enough, to create a thin wet layer, or you have oversprayed it too many times.

Unfortunately this is correct. I've done some quite reasonable paint repairs myself at home, but there's no way I'd attempt this.

Red is possibly the worst colour in the Fiat range for peeling lacquer; we've seen some shocking examples on this forum. It's caused by UV sun damage and there is no economically viable way of repairing this. On a 2010 500 with 134k on the clock, just live with it.

If you're determined, sand it down until every last trace of existing lacquer is removed, then spray a stabilising etch primer (Upol #8 would be my choice), several new colour coats, and then a lacquer on top of that. You need to choose a compatible paint system and adhere to the maximum recoating times between layers. Most of the products that have any kind of durability are highly toxic and are for professional use only with forced air breathing systems in a properly configured spraybooth with full extraction filtration.

Also getting a good colour match on 15yr old paint is challenging, even for the experts.

If you're working at home with cans, your options are not great.

Spraying a rattle can of lacquer onto a 15 yr old sun hardened paint finish in the open air is never going to work, sorry.

I did originally sand it down and remove all the old laquer, i had to sand down again to get rid of the rubbish laquer which i had put on it, which took me a whlie, and had put a new base coat on as well, and i have now managed to re-do the laquer, i had to order some new laquer from a different company which has come up very well, and looks like a profesional finish, the front end of the car was already a shade slightly lighter in colour than the rest of the car, maybe due to previous laquer peeling repair, or accident damage.

It was the laquer that was at fault, not sure if it is old, out of date, or just rubbish laquer, the new laquer has left a nice smooth shiny finish.
