303 Aerospace Protectant is a favourite product of ours that is used during every single detail we perform. In our opinion, it is unbeatable for use as an engine bay dressing and protectant, as it is very easy to apply, dries fully in a relatively short space of time and leaves all plastic, vinyl and rubber surfaces looking like new. It is also a good choice for interior use in cases where a subtle finish (in terms of shine and scent) is required, and makes short work of conditioning rubber door seals too. Whilst the manufacturer claims that it is an excellent choice for use on exterior trims and tyres, our own experiences with it have confirmed that its durability is rather limited under typical British weather conditions, which limits its usefulness in these roles to the summer months only. In short, 303 Aerospace Protectant is very much a staple product in our line up, and one that we heartily recommend to enthusiasts and professionals alike.
303 Aerospace Protectant was originally developed for aerospace and aviation applications, and is one of the most technologically advanced UV screening products on the market today. Unlike many other surface dressings, 303 Aerospace Protectant does not contain oils, waxes, glycerine or petroleum distillates and does not leave behind oily or greasy residues. Instead, it produces a long lasting satin look finish that repels dust, soiling and staining; treated surfaces therefore stay cleaner for longer, reducing the need for future maintenance. 303 Aerospace Protectant is ideal for all plastic, vinyl and rubber surfaces inside and out, and under the bonnet. It gives excellent results on dashboards, door cards, vinyl convertible tops, tyres, exterior trims and engine bay trims, and regular use will prevent the drying, cracking and fading that often results from heat and overexposure of such surfaces to the sun's rays.
For use on engine bays, clean and dry your engine bay first. Then spray 303 Aerospace Protectant liberally over all surfaces, and leave for 4-6 hours to dry. At first you may not believe that this method will work, but trust us it does; it will deliver far superior results compared to trying to dress the same surfaces by wiping on the product with an applicator pad. When you check the results after 4-6 hours, there may still be a few areas that need a quick wipe down with a PB Utility Towel, but everything else will be dry to the touch and looking like new. For use on interior surfaces and door seals, spray 303 Aerospace Protectant onto a Meguiar’s Microfibre Applicator Pad and then wipe down the surfaces to be protected lightly and evenly before allowing them to dry naturally. Do not be tempted to over-apply the product or buff the protected surfaces once dry; neither action is necessary, and both will result in a sub-standard finish.
