The_Doc Posted June 17 Report Share Posted June 17 Hello All, I’ve noticed a number of cracks appearing in the paint work in various places on my TR4. Is this just part and parcel of TR ownership or should I be worried? See below for photos. the paint job was done in 2011, and has stood up quite well. Any advice on how to stop water getting into the cracks and causing rust? Thank you in advance, Adam Quote Link to post Share on other sites
Jase Posted June 17 Report Share Posted June 17 Oooh, I would say that is filler splitting - sorry. Quote Link to post Share on other sites
Malbaby Posted June 17 Report Share Posted June 17 (edited) Poor preparation on the last respray....How much filler/primer was used? Unfortunately, not much you can do now. Edited June 17 by Malbaby Quote Link to post Share on other sites
stuart Posted June 18 Report Share Posted June 18 The lower two pictures are because filler was used on a joint that should have been leaded in and body lines filed back in, movement of the body has cracked the filler/primer, the one on the bonnet is poor prep and probably too much material applied without adequate flash off time. Unfortunately at the moment all you can do to prevent water ingress is to touch the areas in with paint leaving loads of time to dry between applications until youve filled the crack. It wont last long but hopefully till you can afford to have it properly rectified which is to bare metal the areas and start again. Typical 2k flash over. Stuart.

The_Doc Posted June 18 Author Report Share Posted June 18 Thanks all, it was restored and painted by a very reputable TR restoration company, so I might quiz them on the issues and see what they say. As always, your advice is invaluable! Adam Quote Link to post Share on other sites

[Unless they were instructed by you to do a cost saving job and not take the body back to bare metal] Edited June 19 by Malbaby Quote Link to post Share on other sites
Jean-Marie Raedts Posted June 23 Report Share Posted June 23 I have exactly the same phenomenon on the hood which was repainted around 2010. It was repaired for free, but 1.5 years later the problem was back. Heat insulation was then applied to the inside of the hood and everything was sprayed again, this time for a fee. 2 years later, the cracks were back. Should I replace the hood?

Depends on where the cracks are...please detail....the factory hoods were never very well made, and lack some structural integrity. Quote Link to post Share on other sites
Lebro Posted June 24 Report Share Posted June 24 (for hood, read Bonnet !) Quote Link to post Share on other sites
Jean-Marie Raedts Posted June 24 Report Share Posted June 24 The cracks on the bonnet (!) always appear in a different place, in the beginning along the bulge, after the first respray somewhere else on the bonnet and after the third respray and mounting of an Isolation on the inside of the bonnet especially on the edges where there is no insulation . The latter may indicate that journeys in the south in temperatures of over 30 ° C with a hot engine can sometimes make the hood very hot. I don't know if that is the reason, it could also be a jump to conclusion. Quote Link to post Share on other sites

andyhall Posted June 25 Report Share Posted June 25 Another bonnet to add to the thread, mine was painted probably about 18 years ago - Royal Blue , base + lacquer, after about 5 years the paint started to lift around the bulge and has slowly crept since then. Bit like Jean, thought it was heat so added exhaust wrap, started life at the size of a 20p and now like this, really time I got it sorted. Quote Link to post Share on other sites

Again bad prep Im afraid, the hump is always problematical to spray without getting too much material around the sides especially primer. Thats too far back to be engine heat affecting it. Stuart.

Jean-Marie Raedts Posted June 25 Report Share Posted June 25 Although I did not witness the spraying process, I assume the bonnet was reduced to bare metal. Especially with the resprays, they really wanted to prevent it from happening again. The paint shop had a good reputation and employed 20 people. Quote Link to post Share on other sites

I know what short cuts are sometimes taken especially on unpaid remedials. Stuart. Quote Link to post Share on other sites
Malbaby Posted June 25 Report Share Posted June 25 Stuart's last comment is factual. Note....The quality of primers and fillers have come a long way in recent years. Quote Link to post Share on other sites
