    questions Jerome Perkins  on 2023-05-07 14:14:16

    I'm intending to paint my VW T3 using Combicolor paint. However I need to do some bodywork repairs first. What is the best way of protecting the areas I've worked on before I do the whole vehicle? They are small areas so using a roller would be wasteful. Use a brush and then sand it down prior to the final coats? I intend to use the method outlined on the Club 80-90 website for the final coats.

    Answer from Rawlins’ Technical Team: 

    If the vehicle is not being left inside till it is painted fully, we would recommend any area repaired is primed and painted with Rust-Oleum 3369/3380 CombiPrimer Anti-Corrosion followed by Rust-Oleum CombiColor Original.

    Then these areas can be prepared along with the other painted areas when a full repaint is undertaken.

    questions Roland Trickett on 2018-01-29 14:42:35

    We have 2 steel pillars that have been painted in the past with unknown paint. The idea was to strip down to metal and apply Rustolene. Can you give me name of a stripper and paint to apply from your stock. Pillars are about 27inches in circumference and 90 inches tall.

    Answer from Rawlins’ Technical Team: 

    Rust-Oleum Nr.1 Green Paint Stripper would be our suggestion for removing the existing paint, but if the requirement is to just 're-paint' then providing the existing paint is a normal (i.e. not fire retardant, etc.) and well adhered, then it could be just prepared by cleaning and abrading to provide a key and then over painted with something like Rust-Oleum CombiColor, this would negate the need to strip.

    questions MR Adams on 2018-01-03 16:26:39
    Question: Can Combicolour be used for steel beams exposed to the outside. and if so long will the coating last?
    Answer from Rawlins’ Technical Team: 

    Rust-Oleum CombiColor is definitely OK to be used externally on steel, however the exact exposure conditions and degree of surface cleanliness (and profile) at the point of application will be the two biggest factors affecting the overall life expectancy of the coating.

    Assuming preparation is carried out in accordance with the manufacturers data sheets and one coat of Rust-Oleum 3369/3380 CombiPrimer Anti-Corrosion is applied followed by two coats of Rust-Oleum CombiColor we would expect to see a life expectancy of 3-5 years. 

    questions Mr moore on 2016-02-16 16:58:23

    Can Rust-Oleum 3369/3380 CombiPrimer Anti-Corrosion be used outside if overcoated with combicolour gloss?

    Answer from Rawlins’ Technical Team: 

    Yes, Rust-Oleum CombiPrimer can be used on interior and exterior projects and must be overcoated with Rust-Oleum CombiColor to complete the system.
