Car Body Blasting - CTC Powder Coating

Blast Cleaning Car Body Shells

Blast cleaning is a safe and effective way to remove corrosion, fillers, and tired paintwork. Depending on the body and the materials involved, steel or alloy panel work will determine what media we recommend to the client. If the body is steel, then a standard fine-grade steel grit is the standard choice; a fine glass bead is the best option for alloy bodies. Some areas of the bodywork may not be suitable for blast cleaning, such as roofs, door panels, boot lids, and bonnets. These tend to be weaker and may distort under blasting work. Another point to keep in mind is that previous panel beating work will weaken the said panel, and distortion damage may occur.

We do not recommend acid or chemical dipping as this can have some devastating long-term effects on joints and panels that can’t be reached by applying a new protective coat.

Additionally, parts such as suspension/running gear etc, and pipe work should all be removed beforehand,

Underbody work;

Some underseals and stone chip coatings can be very problematic to remove by blast cleaning. Having said that, if any corrosion is hiding under these coats, then the blasting will find the weak areas and remove the sealer. Where it is holding firm, then there really is no need to remove it unless the client prefers to do so. This tends to take a fair amount of time and media to carry out and will reflect in the final cost.

Zinc metalistion;

This is probably the best protection available; being a 99.9% pure zinc hot coat applied with a power ark machine lays down a heavy zinc coat, offering the next best thing to hot dip galvanising without the risk of heat distortion or unwanted zinc deposit build-up. https://ctc-powder-coating.co.uk/metallisation/anti-corrosive-pure-zinc-metallisation-coating/
Once applied, a further prime coat of your choice will seal in the zinc finish completely. Please be aware that the zinc finish will have a light texture; this is a great option for good adhesion to further paint coatings.

Primer work;

MSB offer two types of primer (or you can supply us with your preferred choice)

A standard grey epoxy primer is applied to all reachable parts of the shell, and a black phosphate primer has proven to be a very effective protection for long-term projects. Please see this link for further information.

Other parts;

Chassis, suspension etc. these parts are treated as separate items and would recommend the following coating after prep work https://ctc-powder-coating.co.uk/powder-coating/plascoat/

This VW body pan had the full anti-corrosive treatment.

Schedule of work:
Clean and remove dirt & grease contaminants, blast clean leaving a clean etched & rust free surface.

Apply 100 micron coat of 99.9% pure zinc metallization coating all areas and masking off all threads. Degas to remove any trapped gas built up within the zinc coat.

Remove from the curing oven and apply the first coat of Gloss black Plascoat PPA-571 (no primer coat required) whilst the material is still hot, this helps adhesion to the more difficult parts to reach .Bake off and reapply second hot coat. The overall final coats will be around 300 microns inc zinc coat. The added weight to this will be around 8 kgs.

This system not only gives a high gloss or semigloss finish it also offers extreme long term anti corrosion properties. There are other colours in the range to choose from. Yellow, Blue, Light or dark grey, brown, black, red, green & white.

The overall cost on this project came to £450.00 plus vat. Making the work cost effective and reliable in the long term over the traditional work.

Further information.
The metallization system can be used on most car body parts, motorcycle frames and products used in extreme conditions. . Aluminium panels are not suitable for zinc metallization due to the re-action between the two materials, however a pure aluminium material is used that also offers very good long term protection. Also on offer is. Copper, brass, babbitt and many more materials including pure silver & gold.

Another point to note is for zinc or Aluminium spray can also be used to fill small corrosion damage and pin holes, thus saving time and effort using standard unreliable body fillers. Please note this will not give any structural strength.

For inner surfaces that can not be treated or reached as box rails we can apply a heavy coat of Wax oil to finish the job if required.

So if you are serious and want the best possible long term solution that any car restoration company would be very hard pushed to match then the above system is the one to choose.

MSB would be happy to work alongside any restoration company to advise and offer this service.
