We have applied Speedliner, Ameron and Protecta-kote.
To apply Speedliner correctly requies a large amount of prepairation the outside of the vehicle needs to be masked up with poly sheeting and paper masking to prevent overspray getting onto the bodywork or glass etc. The inside of the vehicle require the same treatment, the vehicle floor then needs sanding down to remove any gloss on the paint, any timber floooring or blemishes on the floor need to be removed eg. glue, rust spots, concrete (in the case of 2nd hand builders vans its not unusual for this preperation to take a full day! then a primer coat needs to be applied by spray gun allowing it to dry to the correct amount then two top coats of speedliner need to be applied. The masking is then removed any blemishes are then worked on to remove them. The vehicle then has to wait to dry out prior to fitting any equipment (in the winter this can take 24 hours +). All the spray equipment has to then be cleaned this takes easily over an hour ( two spray guns, jets, hopper etc.)
We were charging £350.00 for a small van and up to £500.00 for a LWB Sprinter or Transit, the cost of the speedliner, thinners, sanding discs, masking polythene/paper,masking tape, protective erquipment - disposable overalls, air fed mask, over shoes, gloves etc.
capital investment payback on the air compressor, guns, air extractor etc. means their is very little profit in doing the work - no more than £75.00 and a member of staff is tied up for about two days.
Thats why the cost is what it is -
To carry out protecta-kote correctly you still need to mask up the inside, rub down and prepair the surface and apply two to three coats but it can be carried out with through away tools.
All in all Speedliner is tougher but it is also much more tempremental and far greater health and safety care is needed and you need to mix it with a profesional paint mixer also it is supplied as a two pack epoxy that contains Iscocyanates (cyanide).
Appearance wise Protekta-kote can look just as nice if time is spent on preparation and I think it is extremly good value for money.
