The main body of this article was written by Register member John Holmes who rebuilt his 1978 924 over a period of about 5 years.

2. Some cars rust under the trim for the front windscreen, particularly where the clips are positioned to hold the black trim. Inspect carefully and if you don' t wish to remove the screen treat with serious rust liquids and then seal with Plastic Padding PP-FLEX.
3. The black trims around the front windscreen can become damaged, particularly if the bonnet is not adjusted correctly. They are made of aluminium and are a semi matt finish. After working on them to straighten them ready for painting, I used Hammerite Black satin finish from a spray can. This provided a super finish, but beware, you must complete them in under three hours or the paint wrinkles. I used the same finish to repair the door handles, again the three hours for spraying must be met. Remember to remove the plastic strip before spraying.
4. The roof trim either side is a separate piece of metal. The paint work cracks along the join and corrosion can set in. furthermore the trim can become loose at the end and it difficult to tighten. Solution: Using a small amount of Plastic Padding PP FLEX (which comes in a tube) to seal the join and where the trim is loose. This material sets as a hard rubbery flexible seal.
5. The rear rubber spoiler - There become tatty with time and cost a considerable
amount of money and time to replace. I repaired mine (the joins between sections
were gaping and there was a section missing underneath the spoiler where the key had caused the damage. For this later repair I took the whole rear window off
the car). By making little moulds with waxed paper and masking tape. Filling up
the shape under gravity with Plastic Padding PP- FLEX and letting it set (the mould is to ensure that the liquid does not run out while it sets). Also, do it carefully as it is difficult to remove any excess. Having made the repair and careful masking, I sprayed the whole spoiler with a can of WURTH Stoneguard Black which can be purchased in spray cans from professional car paint agents. This is a black rubber underseal paint. Do not put it on too thick, but several thin coats. The final result is excellent and nobody has ever noticed the finish.
6. Rear light clusters - Over the years I found that the four fixing studs had become corroded and some of them were missing. This results in the clusters not fitting snugly to the car. Solution: If you drill out carefully where the stud used to
be and to araldite in a bolt of the right length and size, the head of the bolt can be adequately held so that the cluster can be properly fitted. Take the cluster of the car and take great care to ensure that the bolts are upright when they are being araldited. Use some rust resistant grease (waxoil) on the bolts when re-securing them.
7. Putting on Transfers - Some of the Porsche transfers are long and quite difficult to fit. To allow some degree of adjustment put a small amount of water with detergent on the part of the bodywork where the transfer is to be positioned. Do not push down hard until in the correct position. Then with care press the transfer on ensuring that the detergent water is pushed out from under the transfer.
2. You may not realise it, but the side panels of the car are covered not with plastic but with fine leather. Don' t use plastic cleaners and polishes for them but use leather polish (shoe polish). Black polish bought mine up a treat but I was careful to ensure it was well polished with no black to spoil clothes.

BODYWORK EXTERNAL
1. Bumpers - these are fibreglass and can therefore have minor repairs made to them. One problem is that the driving lights are fitted to the bumper and these are screwed onto the bumper using machine bolts and brass inserts in the bumper. Unfortunately with time these inserts can become damaged and fall out giving poor fixings for the driving lights. Solution: it is possible to obtain replacement inserts through a specialist body firm. These should be araldited back to the bumper having drilled out and cleaned up the fixing position.2.

BODYWORK INTERIOR
1. If you have a black headlining it is now very difficult to obtain the black material. Brown, fawn - yes but not black. Triumph' s also have black headlining and it is possible to obtain the material through Rimmers who are suppliers of Triumph parts (see a Classic Car magazine). The width of the fabric is suitable for a Porsche.2. You may not realise it, but the side panels of the car are covered not with plastic but with fine leather. Don' t use plastic cleaners and polishes for them but use leather polish (shoe polish). Black polish bought mine up a treat but I was careful to ensure it was well polished with no black to spoil clothes.
