SpitfireGeorge Posted June 7, 2020 Report Share Posted June 7, 2020 Hi Guys, Getting my Spitfire Mk3 back from the body shop next weekend after extensive welding. The new panels are fine but some places where metal sheet has been welded in, such as front scuttle and bonnet wheel arches, are in need of some filler to blend them. What filler do you recommend? I have some cellulose putty for those areas requiring very little but other areas need something more substantial. Thanks in anticipation. Cheers.

NonMember Posted June 7, 2020 Report Share Posted June 7, 2020 If there's a fair amount needed, or if it's covering a weld, I try to start with either lead loading (if you're good at it) or a GRP type filler (P40). This keeps the vulnerable bits dry - normal filler isn't waterproof. Then I generally use "Bodysoft" for the final fill up to shape. Link to comment Share on other sites More sharing options...
SpitfireGeorge Posted June 7, 2020 Author Report Share Posted June 7, 2020 Hi, Is the P40 called Isopon supplied by Halfords amongst others and where can I buy Bodysoft? Cheers. Link to comment Share on other sites More sharing options...
NonMember Posted June 7, 2020 Report Share Posted June 7, 2020 Holts Isopon is a brand, and P40 is one of their products. They also make "P38", which is a normal body filler and works OK. The Bodysoft is a professional grade filler, slightly smoother to apply and easier to sand. I bought it from Autopaints of Brighton Link to comment Share on other sites More sharing options...

Having done a few "amateur resprays" over the years, I gave up on cellulose stopper years ago. Now I use this stuff, absolutely superb and much much much easier to use. As to filler, I will be honest I have used several varieties, and found them all to be pretty similar (except one from Toolstation a few years ago that was rock hard and almost impossible to sand) If you want a fibreglass filler, I find Upol Fibral nice to use. The strands are much finer, so easier to get a good finish. I used it over 10 years ago to "bodge" my Toledo roof gutters/roof edge, and still good despite living outside. But in general I would only use fibreglass if there are holes (of any size) Guess I am lucky, Autopaints is literally just down the road from me. And they have a chappie there who is renowned for his paint-matching skills. Way better than the magic-eye machines. Link to comment Share on other sites More sharing options...

It sinks horribly and all the marks you thought you'd hidden will reappear soon after you put the top coat on. Single part stoppers are all a bit prone to this unless only filling tiny defects, but the cellulose ones are the worst. My personal favourite is Upol Dolphin Glaze. This is a two part stopper that is quite fluid so very easy to mix and apply. Also sands easily. Will probably manage up to about 2mm depth. Comes in a bladder-like bag with a screw stopper so easy to reseal and keeps well. For greater thicknesses then P38 is as good as any.

Paul H Posted June 8, 2020 Report Share Posted June 8, 2020 What Primers are members using ? Currently I use https://www.bilthamber.com/paints-and-coatings/highbild Bilthamber Hibuild . It’s only available in aerosol . As I gain more experience would like to use a sprayable primer and my research is leaning towards an epoxy primer .
